The controlled timing of gene expression is crucial to an organism?

Question

The controlled timing of gene expression is crucial to an organism because it allows for which of the following?
A.
differentiation

B.
specialization

C.
development

D.
all of the above

Answer 1

D all of the above

Genes will control when cells become muscle or nerve tissues, which is differentiation. They will control if some cells become liver or intestine, or dermis and epidermis, which is specialization. They will control how big each organ or muscle or tissue gets, which is development.

Answer 2

D. You could imagine that in organisms the regulation of gene expression is critical, even if you know little about the subject. For example, in multicellular organisms, every gene can't be expressed at the same time; the route to multicellularity is through regulation of gene expression. Thus, the answer probably isn't due to just one thing, and in fact all of the above are right (there are other reasons). I'm just trying to help for tests in which you don't know the answer, if you think more than one answer is right, the 'all of the above' answer is usually the correct one.

Answer 3

D
