Answer #1

Answer:

The enzymatic cleavage of a protein in somatic cells of the fish resulting in a fluorescent pigment can be considered as a evolutionary trait. Skin pigmentation of an organism is genetically controlled. The genes responsible for the skin pigmentation mutates many a times and the phenotype resulting from this determines the natural selection of the organism in a specific environment. The favourable phenotype will survive is the environment with higher reproductive success. While, the unfavourable phenotype will have a lower reproductive success. The biochemical or enzymatic cleavage of a protein in somatic cells of the fish is genetically controlled and has been developed with a long evolutionary history.

    A geneticist studying skin pigmentation in zebra fish isolated and sequenced a gene which he believed encoded a blue pigment . The geneticist identified the promoter region of the gene and discovered that the gene carried a 55 base pair untranslated leader sequence and a 34 base pair untranslated trailer sequence. He also analyzed the coding sequence of the gene and discovered that the primary structure of the protein encoded is as follows: met-ile-phe-leu-leu-ile-val-val-ala-pro-thr-ser-ser-pro-arg-ser-gly-trp-cys-arg-leu-met-arg-ser-leu-met-cys How many nucleotides would you expect...
