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.

Answer 1

Muscle and nerve cells differ because they express different genes, despite containing the same genetic material; gene expression regulation allows for cell specialization.

Step-by-step explanation:

Muscle cells differ from nerve cells mainly because they express different genes. Both muscle and nerve cells contain the same set of genes within their DNA, but they do not turn on, or express, the same genes. Different cell types, like muscle and nerve cells, use the expression of different sets of genes to specialize their functions. Despite having the same genetic code and genome, it is the regulation of gene expression that allows cells to differentiate and perform diverse roles within an organism.

Answer 2

Answer: a. express different genes.

Step-by-step explanation:

The nerve cells is functional for controlling the coordination of the body, respond to the external stimuli, voluntary actions in the body. The muscle cells contract and relax to facilitate the locomotion.

All the somatic cells of a living being have the same genomic make up. However, completely differentiated cells of particular tissue lineages express distinct genes, as required so as to perform specialized functions in the body.
