Apeptide has the sequence nh2-phe-pro-lys-gly-phe-pro-cooh. which of the
following sequences in the coding strand of the dna could code for this peptide?
a) 3ʹ uuu-ccc-aaa-ggg-uuu-ccc
b) 3ʹ aug-aaa-ggg-ttt-ccc-aaa-ggg
c) 5ʹ ttt-ccc-aaa-ggg-ttt-ccc
d) 5ʹ ggg-aaa-ttt-aaa-ccc-act-ggg
e) 5ʹ act-tac-cat-aaa-cat-tac-uga

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.

i would have a lunch. it's one big package of food, making it one food. : p

c. movement because i took the test and it lets me review my answers
