Which of the following statements about the regulation of gene expression in eukaryotes is correct?

A. Gene activity cannot be regulated by the packaging of DNA.

B. Gene activity can be regulated by initiation of transcription.

C. Gene activity cannot be regulated by processing of the RNA transcript.

D. Gene activity cannot be regulated by elongation of the RNA transcript.

E. Gene activity cannot be regulated by termination of the RNA transcript.

Homework Answers

Answer #1

Answer) Gene activity can be regulated by initiation of transcription

Explanation- Gene activity or gene expression involves processes such as transcription, mRNA processing, translation, etc. RNA transcript is the copy of DNA which is later translated into proteins for expressing the gene. So gene activity can be regulated by the packaging of DNA, processing of RNA transcript & elongation and termination of RNA transcript. So that options A, C, D, and E are incorrect. The highest level of transcription regulation occurs through the rearrangement of histones (where the DNA are packed). Hence, option B is the correct answer.
