Muscle Cells Differ from Nerve Cells Mainly Because They

Question

Muscle cells differ from nerve cells mainly because they
A)express different genes.
B)contain different genes.
C)use different genetic codes.
D)have unique ribosomes.
E)have different chromosomes.

Accepted Answer

Muscle cells and nerve cells contain the same genes, but they express different genes, leading to the development of different structures and functions. For example, muscle cells express genes for contractile proteins, while nerve cells express genes for neurotransmitters and ion channels. Choice B, C, D, and E are all incorrect because muscle cells and nerve cells use the same genetic code, have the same ribosomes, and contain the same chromosomes.
