Specific Transcription Factorsــــــــــــــــــــــ

Question

Specific transcription factorsــــــــــــــــــــــ .
A)modulate gene expression in response to a specific stimulus
B)are not able to enter the nucleus of eukaryotes and instead help regulate gene expression at the post-transcriptional level
C)bind to target mRNAs prior to translation
D)prevent RNA polymerase II from binding to the DNA

Accepted Answer

Specific transcription factors are proteins that bind to specific DNA sequences and regulate the transcription of genes in response to a specific stimulus, such as a signaling molecule or environmental cue. They can activate or repress transcription and play a critical role in controlling gene expression. Therefore, option A is the correct choice. Options B, C, and D are not accurate descriptions of transcription factors.
