How does gene regulation differ between prokaryotes and multicellular eukaryotes?
A) Different cells vary in the types and number of genes they express in eukaryotes but not in prokaryotes.
B) Protein-DNA interactions occur only in eukaryotes.
C) Protein-DNA interactions occur only in prokaryotes.
D) Cell-specific gene expression and protein-DNA interactions both occur only in eukaryotes.
E) Cell-specific gene expression and protein-DNA interactions both occur only in prokaryotes.

Question

Quizplus · Accepted Answer

In multicellular eukaryotes, different cells can have different gene expression patterns, leading to specialization of function. This is not the case in prokaryotes where all cells in the same species have the same DNA content and express the same set of genes.

Option B and C are not correct as protein-DNA interactions occur in both prokaryotes and eukaryotes.

Option D and E are not correct as cell-specific gene expression and protein-DNA interactions occur in both prokaryotes and eukaryotes.
