Answer:
Answer is sigma.
Explanation:
The sigma factor can be described as protein regulating transcription in bacteria. That is, it enables the synthesis of RNA at specific locations in DNA. This specific location is known as promoters.
The sigma factor is also known as specificity factor, because, it is specific for the gene.
Transcription can be explained as the process by which genetic information in the DNA strained are copied into a new molecule of mRNA, through the aid of RNA polymerase.
It should be noted that, when there is an increase in pressure, at constant temperature, the stability of elongation complex will decrease. This means that, temperature determines the pressure at which transcription elongation stops.
