       Questions and Answers About the Merger
       Will the common stock of the combined company trade on an exchange?,
page 5

   1.                                                   You disclose that
CohBar has filed a listing application for the combined company   s
                                                        common stock with
Nasdaq and that it is expected that such common stock will trade on
                                                        the exchange. We also
note Section 7.1(d) of the Merger Agreement provides that the
                                                        approval of the listing
of the additional shares of Parent Common Stock on Nasdaq shall
                                                        have been obtained.
Please revise the Q&A and the Letter to Stockholders to clarify
                                                        whether the closing of
the merger is conditioned upon Nasdaq   s approval of the listing
                                                        application. Disclose
whether this condition is waivable and if so, indicate whether
                                                        Nasdaq   s
determination will be known at the time that stockholders are asked to vote to
                                                        approve the merger.

equity will not recognize
         any gain or loss for U.S. federal income tax purposes as a result of
the merger.
Prospectus Summary
CohBar, page 9

3.       With reference to your disclosure on page 211, please revise the
Summary and the Q&A if
         appropriate to explain that if the merger is completed, the combined
company will focus
         on developing Morphogenesis    product candidates, and it is
anticipated that the combined
         company will not continue to develop CohBar   s legacy product
candidates. Also, revise
         the second Q&A on page 4 to provide context for the discussion of the
CVRs.
Morphogenesis, page 10

4.       We note your disclosure referencing potential FDA accelerated approval
designation and
         entry into a Special Protocol Assessment (SPA) Agreement. Revise to
balance your
         Summary disclosures by clarifying that Morphogenesis' candidates have
not qualified for
         such designation and that there is no guarantee that such designation
will be granted. Also,
         revise to clarify that entry into an SPA Agreement with FDA may not
lead to faster or
         less costly product development or a regulatory review or approval
process, and does
         not increase the likelihood that your product candidate will ever
receive marketing
         approval.
5.       We note your disclosure that Morphogenesis is a Phase 2/3 clinical
stage immuno-
         oncology company. In light of your disclosures on page 219 and
226-228, please remove
         the reference and clarify that your Phase 1b trial is on-going.
6.       Please revise your discussion of the Merkel cell carcinoma program to
highlight and
         explain the following:
             Clarify the number of Merkel cell carcinoma patients that have
been treated to date
             with the IFx-Hu2.0 cancer vaccine product candidate and briefly
discuss the
             treatment response.
             Disclose the estimated US Merkel cell carcinoma patient
population.
             Explain the term "adjunctive therapy."
The FDA or comparable foreign regulatory authorities may disagree with
Morphogenesis
regulatory plans..., page 58

7.       Please revise the risk factor to explain, if true, that Morphogenesis
plans to obtain
         accelerated approval designation for some or all of its product
candidates under the
         accelerated approval pathway and the impact to the company if
accelerated approval does
         not materialize.

U.S. federal
         district courts are the exclusive forum for any complaint asserting a
cause of action arising
         under the Securities Act. Please revise your disclosure to state that
there is uncertainty as
         to whether a court would enforce such provision. In this regard, we
note that Section 22
         of the Securities Act creates concurrent jurisdiction for federal and
state courts over all
         suits brought to enforce any duty or liability created by the
Securities Act or the rules and
         regulations thereunder.

The Merger
Background of the Merger, page 106

10.      Please revise the disclosure on page 107 to disclose the terms of
Morphogenesis' initial
         non-binding indication of interest. Clarify whether CohBar management
identified
         Morphogenesis as one of the top merger candidates as of November 8 and
one of the top
         three candidates as of November 15. To the extent that CohBar
management did not
         view Morphogenesis as the top or one of the top candidates, please
discuss the reason(s).
11.      Please revise to discuss in greater detail the negotiations concerning
the contingent value
         rights and the stock purchase agreement with K&V Investment One.
12.      Please also revise this section to explain the diligence that CohBar's
management, board
         and advisors conducted concerning Morphogenesis.
13.      With reference to the February 13, 2023 entry, describe the material
differences between a
         traditional staggered sign-and-close reverse merger and simultaneous
sign-and-close
         reverse merger structure. Explain which party sought the simultaneous
sign-and-close
         structure and why. Also indicate when Mr. Fitzgerald first raised his
concerns with this
         proposed structure.
14.    We refer to the May 10, 2023 entry. Please revise to quantify the
expected reduction to the
       net cash that CohBar would deliver under the staggered sign-and-close
structure relative
       to the previously planned simultaneous sign-and-close structure. Explain
how the parties
       concluded that Morphogenesis's valuation should be increased from $125
million to

       $130.6 million based on this decision. In this regard, it is unclear why
the structural

enterprise value
         ascribed to CohBar was derived.
16.      Please tell us why the expected cash balances are blank. In this
regard, please clarify
         whether the disclosure in the section reflects the board's view as of
May 23
         when it approved the merger agreement or whether the disclosure
reflects its expectations
         at a different point in time.
Morphogenesis' Reasons for the Merger, page 120

17.      Please tell us whether, and if so why, the Morphogenesis Board
considered the additional
         financing to be received under the Securities Purchase Agreement to
consist of additional
         financing "committed" from the Initial Financing and Second
Financing." In this regard,
         we note based on your disclosure on page 2 and elsewhere that the
Second Financing
         would occur, if ever, at the option of the Investor.
Opinion of CohBar's Financial Advisor, page 123

18.      We note the disclosure on page 123 indicating that CohBar hired
Ladenburg to render an
         opinion as to the fairness of the Exchange Ratio, from a financial
point of view, to the
         holders of CohBar Common stock. Accordingly, please provide
Ladenburg's analysis
         regarding the $25 million implied valuation of CohBar or advise.
19.      We note your disclosure indicating that Ladenburg reviewed relevant
financial and
         operating data provided by CohBar and Morphogenesis as well as
"certain internal
         analyses." Please revise to clarify whether Ladenburg considered or
utilized any financial
         or operating data to conduct one or more of the three principal
financial analyses. If not,
         then also explain why it did not do so and further explain if/how this
data factored into
         Ladenburg's fairness determination .
20.      We note your references to "considerations and judgments" concerning
historical and
         projected financial and operating characteristics and other factors
that could affect
         the value of the Selected Publicly Traded Companies, Selected
Precedent IPO Companies,
         target companies from the Selected Precedent M&A Transactions and
Morphogenesis to
         which they were being compared. Please revise your disclosure in this
section to describe
         such considerations and judgments made by Ladenburg in its comparable
company and
         precedent transaction analysis.

Implied Morphogenesis Valuation, page 125

21.      Please provide the following information regarding Ladenburg's
derivation of an implied
         valuation for Morphogenesis of $130.6 million.
             Provide a reconciliation of the number of Morphogenesis shares of
common stock on
             a "fully diluted, as converted treasury stock method basis" as
discussed on page 125

stock, warrants and
             stock options that were outstanding at March 31, 2023.
             Explain how you determined the $0.62 per share value for
Morphogenesis common
             shares.
             Provide an illustration that shows how the 0.3114 Exchange Ratio
was determined.
             Confirm expected timing for the reverse stock split, which you
appear to indicate will
             occur prior to or on the merger date, as discussed on page 263.
Director Positions Following the Merger, page 131

22.      We note your disclosure concerning the two directors appointed by
CohBar. We also note
         the disclosure on page 131 concerning Mr. Fitzgerald's May 3, 2023
statement that he
         would not resign from the board at closing. Please revise or advise to
clarify Mr.
         Fitzgerald's role, if any, in the combined company following the
closing of the merger.
Material U.S. Federal Income Tax Consequences of the Merger, page 136

23.      Please include a tax opinion covering the material tax consequences
of: (i) the merger to
         United States holders of Morphogenesis capital stock, (ii) the merger
to United States
         holders of CohBar capital stock and (iii) the issuance of CVRs to US
holders of CohBar
         capital stock. For guidance, refer to Staff Legal Bulletin No. 19
(Oct. 14, 2011).
24.      With reference to the disclosure on page 137, please tell us whether
there is significant
         doubt regarding whether the Merger qualifies as either a
"reorganization" or a
         "contribution."
Material U.S. Federal Income Tax Consequences of the CVRs..., page 138

25.      To the extent that there is a lack of authority directly addressing
the tax consequences of
         the transaction, conflicting authority or significant doubt about the
tax consequences of
         the transaction, counsel or accountant may issue a    should    or

         highlight the tax consequences to the prospective CVR holders as

28.      The pipeline table here and on page 225 should graphically reflect the

practicable date, as well as
         the material stages you will need to complete before marketing your
products.
         Accordingly, please revise the tables to reflect that your IFx-2.0
candidate targeting
         advanced or metastatic Merkel cell carcinoma (   MCC   ) remains in
Phase 1b. In this
         regard, your disclosures on pages 219 and 227-228 indicate that this
trial is on-going and
         that you only have preliminary results from that trial. Similarly, the
arrow for IFx-2.0 in
         metastatic cancers indicates that the Phase 2 basket trial is underway
even though your
         disclosure on page 218 indicates that Morphogenesis is "planning" the
Phase 2 basket
         trial for Q4 2024. Also, revise the "Highlights" column to reflect
that Morphogenesis must
         identify a lead candidate for IFx-3.0.

the reference to

elsewhere as
         appropriate, to explain that evidence of clinical activity and/or
clinical response does not
         mean that the product candidate has or will demonstrate clinical
efficacy or that it will
         prove to be safe as required to receive regulatory approval.

Pathway, page 226

33.      Please revise the heading so that it does not imply that you have

34.      Explain briefly why you identify the prospective trial as a Phase 2/3
as opposed to a Phase
         2 trial.
35.      With reference to your disclosure on pages 243-244, please revise to
disclose the basis on
         which you plan to seek accelerated approval. In this regard, please
clarify whether you
         will seek approval by (i) establishing that the drug product has an
effect on a surrogate
         endpoint that is reasonably likely to predict clinical benefit and/or
(ii) that the drug
         product has an effect on an intermediate clinical endpoint that can be
measured earlier
         than an effect on irreversible morbidity or mortality, or IMM. Also,
revise the table on
