What is the function of the primers in PCR? What is the function of the primers in PCR? They are the monomer building blocks fro

m which the DNA strand is synthesized. They provide energy for the DNA polymerization reactions. They provide a 3’ end for the DNA polymerase. They polymerize free nucleotides to form the new DNA strands.

Answer:

<h2>They provide a 3’ end for the DNA polymerase.</h2>

Explanation:

Polymerase chain reaction (PCR) is an in-vitro method to making copies of a specific DNA sample in a very short time.  

Polymerase chain reaction was invented by Kary Mullis in 1983.

Primers are specific to the DNA which we want to replicate and they bind to the specific sequence which is complementary to it. Primers provide a 3’ end for the DNA polymerase.

3. Describe the benefits and drawbacks of experiments in a laboratory compared to experiments done in a
labwork [276]

Answer:

Benefits:

In  a lab, scientists can control the conditions according to their research and study. This allows them to focus on a single perspective.

On the other hand, in a natural setting there are complex interactions due to which focusing on a single attribute can be difficult.

Drawbacks:

Ina  laboratory experiment, we cannot control every variable which might be having an effect on our concerned subject as compared to a natural setting. This is because lab experiments are performed in a controlled experiment. Hence, there might be difference of results in a lab experiment and nature.

An oligomeric enzyme transitions from a T to R state as substrate binds, producing positive cooperativity. If a heterotropic all
V125BC [204]

Answer:

Increase

Explanation:

Oligomeric enzyme have more than one polypeptide chain and the enzyme show positive cooperativity. It means that binding of the ligand to the enzyme will help other ligands to bind to the enzyme. Hill cofficient is used to measure the determining the degree of cooperativity of the binding between enzyme and substrate or ligand. As in this case, allosteric enzyme show positive cooperativity, its Hill cofficient will increase

MrRissso [65]

Answer:

D) Insulin

Explanation:

Insulin is an organic molecule, specifically a protein molecule, which is produced by the pancreas. It is an enzyme that regulates the level of glucose in the blood. Insulin carries out this function by converting excess glucose in the blood into a stored form called GLYCOGEN.

The glycogen, which is stored in the liver, is converted back to glucose when the need arises for glucose in the blood. Hence, INSULIN is that large organic molecule (protein) that helps to maintain glucose levels in the blood and is released from the pancreas.
