The reason for differences in the sets of proteins expressed in a nerve and a pancreatic cell of the same individual is that nerve and pancreatic cells contain different
A) promoter- proximal elements.
B) sets of regulatory proteins.
C) genes.
D) promoters.
E) regulatory sequences.

Question

Quizplus · Accepted Answer

Nerve and pancreatic cells contain the same genes but express different sets of proteins because they have different sets of regulatory proteins. These regulatory proteins influence the expression of genes specific to the function of the cell type, leading to the differences in protein expression between cell types.
