Answer:

The correct answer will be option-B.

Explanation:

Transfer RNA or tRNA is the RNA molecule associated with the protein synthesis as it adds the specific amino acids to the nascent growing polypeptide.

The structure of the tRNA molecule resembles the shape of a clover leaf and is known as the clover leaf model. The structure contains hydrogen-bonded stems and associated loops. The stems include acceptor stem which posses CCA 3'-terminal group to attach amino acids. The anticodon loop contains an amino acid attachment site. T and D loop contains modified pseudouridine and dihydrouridine.

Thus, Option-B is the correct answer.

The relative location of four genes on a chromosome can be mapped from the following data on crossover frequencies Genes B and D

kykrilka [37]

Answer:

3. CABD

Explanation:

The gene mapping refers to providing position to the genes on the chromosomes. The first gene map was constructed by the Alfred Sturtevant on the basis of recombinant produces or recombination frequency which was calculated.

The gene mapping refers to providing position to the genes on the chromosomes.

In the given question to construct gene map:

1. Look for the highest recombination frequency that is 50% between the C and D.

2. Now look for second-highest value and place the gene accordingly.

3.Similarly, place the genes in the decreasing order of recombination frequency and this will result that the sequence of the genes is- CABD.

Thus, Option-3 is correct.

The backlit screens of computers emit enough light to suppress the hormone _____, which normally rises in the evening and orches

san4es73 [151]

The backlit screens of computers emit enough light to suppress the hormone melatonin. This hormone rises in the evening and orchestrates daily rhythms.

<h3>What is melatonin?</h3>

Melatonin is a hormone whose secretion in the brain is connected to sleep (i.e. the time of day or circadian cycle).

Melatonin is produced by the pineal gland as an environmental response to darkness.

This hormone (melatonin) is well known to be involved in different sleep disorders, thereby having therapeutic applications.
