Which of the following is NOT a way in which gene expression is regulated?

Group of answer choices

Rate of DNA replication

Alternative 3' cleavage

Rate of transcription

Intron splicing

Solutions

Expert Solution

Option a is not a way to regulate gene expression , RATE OF DNA replication.

Rate of DNA replication does not effect expression means formation of protein. Replication involve formation of DNA form preexisting DNA molecule.

While rest of other involve in gene regulation

Cleavage and polyadenylation (C/P) is essential for maturation of the 3′ ends of mRNAs. And here regulation can occur impacting mRNA metabolism. ...

Rate of transcription directly affect gene regulation. Increse rate of transcription leas to increase gene expression, while decrease rate of transcription lead to decrease expression of gene. This is done with help of promoter, various cis and trans regulatory elements.

Intron splicing also play in important role in gene regulation. Some of intron regulate activity of mRNA .
