Question

a gene is bound with a positive transcription factor. what effect does this have on the gene? (hint: is this going from dna to mrna, or mrna to dna polymerase?) (1 point)

this turns the gene on, allowing for transcription

this turns the gene off, preventing transcription

this turns the gene off, preventing translation

this turns the gene on, allowing for translation

Explanation:

Transcription factors are proteins that regulate gene expression. A positive transcription factor promotes gene expression. Transcription is the process of making mRNA from DNA. When a positive transcription factor binds to a gene, it "turns on" the gene, enabling transcription (DNA to mRNA). Translation is the process of making proteins from mRNA, which is a later step. Negative transcription factors would prevent transcription (turn the gene off).

Answer:

This turns the gene on, allowing for transcription
