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

Question

Quizplus · 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.
