Ans.
Codons are three nucleotide sequences present on DNA or RNA that codes for the amino acids or provide stop signal at the time of protein synthesis. Each codon codes for a specific amino acid. The amino acid proline (pro) is coded by CCG, CCT, CCA, and CCC; aspartate (asp) is coded by GAT and GAC; glycine is coded by GGA, GGG, GGT, and GGC; and lysine is coded by AAA and AAG.
Thus, the correct answer is 'option D). CCA-GAC-GGC-AAA.'

Respiratory system is refers to as the organs which are involved in breathing such as nose, throat, larynx, trachea, bronchi, and lungs. It is also known as respiratory tract.

What is breathing?</h3>
When person inhale (breathe in), air enters in the lungs, and oxygen from atmosphere moves to body blood. At the same time, carbon dioxide, a waste gas, moves from blood to the lungs and is exhaled (breathed out).
Breathing process is known as gas exchange which is is essential to life.

Active transport is the movement of molecules or ions against a concentration gradient. Passive transport is the movement of molecules or ions from an area of higher to lower concentration.
Passive transport does NOT require energy
-Diffusion - small uncharged molecules
-Osmosis - water
-Facilitated diffusion - glucose
Active transport REQUIRES energy
-Ion pumps
-Endocytosis
-Exocytosis
When two parents are purebred it means that they are homozygous for the characteristic that's being tested (in this case the fur colour). When they are crossed, the offspring will obligatory be heterozygous, an allele of each type from its parents. So, the trait that comes up will be the dominant trait, while the recessive trait will be hidden.
