BS question AAMC 6R

[TXKnight]

---

Members don't see this ad.

can anyone please tell me why I got this one wrong?
It's item #175, part of a passage that talks about gene therapy and other stuff. Is part of AAMC 6R.

175 - Would an exogenous gene introduced into somatic cells be passed from parent to offspring?

A. Yes, because the DNA will be localized into the cell's nuclei
B. Yes, because all DNA is passed from parent to offspring during meiosis
C. No, because changes to somatic cells are not passed to offspring
D. No, because foreign DNA is not passed to offspring

Post what you would choose and I will post the answer I picked a little later . I made my choice and it turned out to be wrong according to the answer key and I can't figure why? I consider myself doing fine in bio but maybe I should reconsider?

some insights would be appreciated with your answer.

I would pick C ... wats the answer

 

[Ssina]

yeah I think C too

Well to your astonishment and mine:

I picked C as well, correct answer A. I really believe this is a mistake --UNLESS- they talk of offspring as in that same cell undergoing mitosis once the gene has been integrated and the daughter cells being called offspring (which i think is incorrect). However, there is nothing in the passage that would indicate that AND it's very tricky. I really think is C.

I thought C as well. I get what you're saying about the daughter cells, but I've never heard the words "parent" and "offspring" associated with somatic cells.

Must be an error, unless the passage says something about the exogenous trait being used in recombination..?

yep its C ... here my Kaplan explanation says for 6R

The only cells that are passed from parent to offspring are the germ line cells (eggs and sperm). All other cells are
somatic cells and are not passed on to the next generation; thus, a gene introduced to a somatic cell could not be passed on
to offspring (choice C is true, and choices A and B are false). Furthermore, any DNA contained within a germ line cell, be
it original cellular DNA or introduced DNA, will be passed on (choice D is false).

Oh, this is a Kaplan practice test, not an AAMC?

its the kaplan explanation for aamc 6r

its the kaplan explanation for aamc 6r

Thank you for showing that, I was starting to believe i had this simple somatic/germ cell thing wrong in my head. I don't have the Kaplan explanations to it I just have the paper test (older one) and they don't have explanations, only the key. I triple checked the number and the correct answer so AAMC must have had that answer key printed wrong.......makes me wonder if in the real MCAT are mistakes like that? ...😕
