Answer:

(1) enzymes

Explanation:

It is restriction enzymes specifically, which are used to cut DNA into fragments. Restriction enzymes can be regarded as biological scalpels which can produce either a blunt end or sticky end in DNA. The main characteristic feature of restriction enzymes is that they cut a DNA at a specific location which is known as restriction site. The restriction sites are located in multiple cloning site (MCS) region of chromosome. Some of the examples of restriction enzymes are EcoRI, BamHI, HindIII etc.

When we cut the DNA in small fragments, these fragments can be easily spotted in gel electrophoresis which gives us an idea of their size.

Researchers who have studied color blindness and color deficiency have found that a total color blindness is extremely rare in a
Schach [20]

Answer:

Option-B

Explanation:

Color deficiency is a condition caused when the person is not able to distinguish the different colors. Since the person is not able to distinguish different color, therefore, the chromo-receptors which are affected are the cone cells located in the retina which allows us to see different wavelengths.

1. Total color blindness is not a rare disease in animals.

2. Total color blindness in which a person is not able to see any color occurs when all types of cone cells become malfunction or completely absent.

3. The red-green color blindness is more common than the blue-yellow color blindness.

4. The mother is usually not affected as she is the carrier of the gene responsible for the color blindness.

Since all options except Option-2 are incorrect therefore option-2 is the correct answer.
