Answer 1

gggggg ccccc and uuuu is the adom for the body type in blood

Answer 2

The correct answer is: C) 5ʹ TTT-CCC-AAA-GGG-TTT-CCC

phe-phenylalanine codons: TTT, TTC

pro-proline codons: CCT, CCC, CCA, CCG

lys-lysine codons: AAA, AAG

gly-glycine codons: GGT, GGC, GGA, GGG

phe- phenylalanine codons: TTT, TTC

pro- proline codons: CCT, CCC, CCA, CCG

The process of translation occurs in the cytosol, on the ribosome. The mechanism consists of the addition of one amino acid at a time to the end of the polypeptide being formed. Each amino acid should match to a three nucleotide subsequence of the mRNA (codone). During the process of translation (synthesis of proteins) ribosomes move from 5’ toward the 3' end of mRNA.
