Question

if most of an organisms cells have the same dna, why is it true that all cells do not make the same proteins?
○ because of chromosome pairing
○ because of differentiated mrna
○ because of dna mutation
○ because of gene regulation

Explanation:

All cells in an organism share identical DNA, but they produce distinct proteins due to gene regulation. This process controls which genes are turned "on" or "off" in specific cells, leading to specialized protein production. Chromosome pairing is unrelated to this specificity, differentiated mRNA is a result rather than a cause, and DNA mutation is not the general reason for normal cell specialization.

Answer:

○ because of gene regulation
