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.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

the correct answer to this question is #5
