Question

Cellular differentiation within a specialization within a multicellular organism is possible because...

A. the cells of a multicellular organism contain different DNA
B. the cells of a multicellular organism have the same DNA, but turn on and off different genes according to function
C. the ribosomes are different from cell to cell, providing cell differentiation and specialization
D. the golgi body takes over cell function, providing cell differentiation and specialization

Answer 1

Im not really sure but i believe it is D

Answer 2

B

Answer 3

I am positive it's B. It cannot be D because not all cells go to the golgi, some stay in the nucleus etc... Everything is in the genes, the genes do indeed turn on and off and that is how they are instructed to become the cell they have to differentiate into

Answer 4

B is correct, but liz's explanation makes no sense. cells can't "go to the golgi" since the golgi (and nucleus for that matter) are organelles of a cell.

Answer 5

During cellular replication. Why do cells have an NLS?I agree my wording might not make sense to someone who is barely getting into bio

Answer 6

Once again Liz, cells can't "go to the golgi or nucleus" simply because these are organelles of a cell. It's analogous to you not being able to go into your stomach because your stomach is an organ that is a part of you. The NLS (nuclear localization signal), I suppose is what you're referring to, is for proteins.

Your wording doesn't make sense simply because it's wrong and for no other reason.
