Concept explainers
a.
A transcription factor is a protein that controls the degree of genetic information transcription from DNA to messenger RNA (mRNA) through binding to a particular DNA sequence. The essential function of the transcription factor is to regulate (turn off or turn on) the genes in order to ensure that they are expressed in an exact cell at an exact time and exact amount throughout the life.
