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.
Answer: 320 phosphate groups.
<u>Each nucleotide of DNA contains one phosphate group attached to it</u>.Therefore if there <u>were 160 nucleotides in a strand;,definitely each nucleotide of the strand must contain one phosphate group, therefore 160 phosphate groups. must be present.</u>
However, a DNA molecule must contain double strands, therefore 160 multiplied by 2 should give 320 phosphate groups in the alien DNA.

Answer:
The sun's solar radiation and the wind's movements.
Explanation:
The heat from the sun and air movement is responsible for the weather on Earth. All-weather takes place in the lowest layer of the Earth's atmosphere, which is a gaseous layer that surrounds the planet. The heat of the sun causes the air in this layer to warm to various temperatures in different regions.
