How is the enzyme ligase beneficial in genetic engineering?

1 answer:

6 0

The name comes from a latin word meaning to glue or bind together. DNA ligase catalyses the joining of DNA fragments (usually those produced by restriction enzymes). Thus different genes can be put into vectors and moved into other hosts.

ehidna [41]

First, deoxygenated blood flows into the right atrium of the heart from the inferior and superior vena cava.

Blood then flows through the bicuspid valve and into the right ventricle.

The blood then flows through the pulmonary valve and into the pulmonary artery. Arteries carry blood away from the heart while veins return blood to the heart. The pulmonary artery is on of the only arteries that carries deoxygenated blood.

Blood will then pass through the lungs and will be oxygenated.

After being oxygenated, the blood enters the pulmonary veins. The pulmonary veins are some of the only veins that carry oxygenated blood.

Blood enters back into the heart through the left atrium.

Then, blood flows into the left ventricle through the mitral valve.

Finally, blood is pumped through the aortic valve, into the aorta, and is distributed throughout the body.

timofeeve [1]

Answer:

1 DDRR - Red, non-dexter

2 DDRr - Roan, non-dexter

2 DdRR - Red, dexter

4 DdRr - Roan, dexter

1 DDrr - white, non-dexter

2 Ddrr - white, dexter

Explanation:

Dexter is deleterious in homozygous condition, hence, phenotypes are heterozygous.

Roan are also heterozygous.

If dexter allele is represented by D, non dexter individuals will be DD dexter individuals will have the genotype Dd.

If colour in cattle is represented by R, red individuals will be RR, white will be rr, then roan colour will be Rr.

Hence, roan dexter cow and roan dexter bull will both have DdRr genotypes.

Crossing the two: DdRr x DdRr

Progeny:

1 DDRR - Red, non-dexter

2 DDRr - Roan, non-dexter

2 DdRR - Red, dexter

4 DdRr - Roan, dexter

1 DDrr - white, non-dexter

2 Ddrr - white, dexter

Others that are either aborted or stillbirths include:

1 ddRR

2 ddRr

1 ddrr
