                                                        final approval of your
Nasdaq listing. Please ensure the disclosure is consistent with your

         based genome editing technologies, recombinase DNA and RNA gene
writing, epigenetic
         editing, etc. Please explain your belief that your toolbox "uniquely"
positions you to
         access the entire genome when you have indicated that there are
private companies about
         which little is known.

4.       Please increase the font size of the text within the table.
5.       Please remove the statement claiming your base editors will accelerate
therapeutic
         development, as it appears speculative.

6.       Please revise this graphic to separate the "Clinical" column into
Phase I, Phase II and
         Phase III to clearly represent what development stages must be
completed prior to
         commercialization of your therapeutic candidates. In addition, please
combine your
         columns labeled "lead optimization" and "IND-enabling" into one
preclinical development
         column.
7.       We note the inclusion of therapeutic candidates for renal disease and
         autoimmune/immuno-oncology in your pipeline table. Given the limited
disclosure
         related to these programs, please explain why they are sufficiently
material to your
         business to warrant inclusion in your pipeline table. If they are
material, please expand
         your disclosure in the Business section to provide a more fulsome
discussion of these
         programs, including a description of development activities conducted.
Alternatively,
         remove any programs that are not currently material from your pipeline
table on pages 4
         and 158.


8.       We note that the gene for cardiovascular disease is "undisclosed." If
this gene has been
         determined, please revise your table, to identify the gene and
describe this program.

9.       We note the following disclosure from page 223: "The grant date fair
value of all awards
         made under our 2023 Plan and all other cash compensation paid by us to
any non-
         employee director in any calendar year for services as a non-employee
director shall not
         exceed $       ; provided, however, that such amount shall be $
for the calendar year
         in which the applicable non-employee director is initially elected or
appointed to the board
         of directors." Please revise hereunder to disclose the extent to which
any stock-based
         compensation has been awarded during 2023 (also noting the grants in
March and June
         2023 as disclosed on page F-43) and provide the fair valuations of
each award. Once you
         have an estimated offering price or range, please explain to us how
you determined the
         fair value of the common stock underlying your equity issuances and
the reasons for any

         differences between the recent valuations of your common stock leading
up to the initial
         public offering and the estimated offering price. This information
will help facilitate our
         review of your accounting for equity issuances including stock
compensation.

10.      Please remove references to your genome editing systems potentially
being "best-in-class"
         and "first-in-class" as it does not appear that your platform has
resulted in any FDA
         approved therapies and future approved therapies are speculative.
Moderna Strategic Collaboration and License Agreement, page 181

11.      We note your disclosure stating you are eligible to receive royalties
ranging from a mid-
         single digit to a "low double-digit" percentage of annual net sales
from licensed products.
         As drafted, it is unclear if "low double-digit" refers to a range
within ten percentage points
         of a mid-single digit percentage. Please revise your disclosure to
limit the royalty range to
         ten percentage points.
12.      Given your disclosure that you received a non-refundable upfront
payment of $40.0
         million, a $5.0 million payment for the first year of research costs,
Moderna's obligation
         to reimburse you for up to $5.0 million in annual research and
development costs, your
         eligibility to receive development, regulatory and sales milestone
payments and royalty
         payments, explain the statement that you will work with Moderna on the
co-development
         and commercialization of products with respect to the DT Co-Co program
and share costs
         and profits equally. Explain how sharing profits equally is consistent
with a royalty
         provision. Will the milestone payments be considered part of Moderna's
share of the
         costs? Will the royalty payments to Metagenomi be considered part of
its share in the
         profits?
Our License and Collaboration Agreements, page 181

13.      For each agreement discussed in this section, please disclose the
aggregate amounts paid
         to date and the aggregate amount of remaining potential payments under
each agreement.
Affini-T Development, Option and License Agreement, page 182

14.      Please file the Development, Option and License Agreement entered into
with Affini-T as
         an exhibit to your registration statement or tell us why you do not
believe such a filing is
         required.
15.      Explain the distinction between a regulatory milestone and
developmental milestone.
         Additionally, given that you are eligible to receive a milestone of
933,650 based on an
         achievement of a regulatory milestone event, regardless of the value
of the shares at the
         time of the event, please disclose the trigger event or tell us why
you believe such
         information is not material.
