Answer:
sigma subunit
Explanation:
Sigma subunit of RNA polymerase holoenzyme directs the enzyme towards the consensus sequences present upstream of the transcription start site. Completion of the initiation phase of transcription is followed by dissociation of sigma subunit from the transcription complex.
The protein NusA replaces the sigma subunit. The RNA polymerase leaves the promoter and starts the elongation
.
<span>The action of Helicase is to create replication forks and replication bubbles. Helicase is the first step in the DNA replication process. Helicase is an enzyme that breaks the hydrogen bond between the parental DNA to free the DNA double helix. The area where it unwinds is called as replication fork.</span>
The correct answer is that ammonia is removed from the blood by the liver, which processes it into urea, and discharging it into the circulation.
The liver plays an essential function in the metabolism of proteins. The cells in the liver modify amino acids in foods so that they can be utilized to generate energy, or make fats or carbohydrates.
A toxic component known as ammonia is a waste-product of this procedure. The liver cell transform ammonia to a much less toxic component known a urea, which is discharged into the blood. Urea is then translocated to the kidneys and is removed out of the body in the form of urine.
