Why are single-stranded binding proteins necessary for DNA replication?

Biology
1 answer:
Margarita [4]3 years ago
8 0

Answer:

d.They prevent the two parental strands from coming together again.

Explanation:

During the process of DNA replication, the two DNA strands should be separated from each other to serve as a template. To separate the two DNA strands, the helicase enzyme breaks down the hydrogen bonds between the complementary base pairs of the DNA strands. The process uses ATP as a source of energy.

Due to the presence of complementary base pairs, the separated DNA strands have a tendency to reanneal by the formation of hydrogen bonds. To prevent the reannealing of separated DNA strands, single stranded binding proteins bind to them. Binding to single stranded binding proteins to the separated DNA strands does not allow them to reanneal.

Investigators wish to purify an enzyme—a serine protease—using affinity chromatography. They attach to the matrix of an affinity
Dennis_Churaev [7]

Answer:

After this treatment, the investigators should expect to get a mixture of the desired enzyme, plus fragments of the peptide used to desorb the enzyme in question.

This would be the result of using a peptide as a desorption solution when the desired protein is a protease,

Assuming that the protease retains its activity in the medium in question, and that the peptide can act as a substrate (which would make sense), as the peptide solution is added, it will interact with and bind to the antibody, but some molecules will also interact with the active site of the enzyme as it desorbs and passes through, culminating on the elution of the hydrolized part of the peptide along with the enzyme.
