Use the Amino Acid Chart on this page to answer the questions below.

Transcription – Translation (transcribe to mRNA, then decode for amino acids)
DNA: TAC GCG AAT ATC

a A) START – Lysine – Leucine – Glycine
b B) START – Arginine – Leucine – STOP
c C) START – Serine – Cysteine – Phenylalanine – STOP
d D) Methionine – Lysine – Leucine – STOP

Answer 1

The right answer is B) START – Arginine – Leucine – STOP .

RNA transcribed from this DNA consists of: AUC - CGC - UUA - UAG.

AUC is the start codon.

CGC codes for Arginine.

UAA codes for Leucine.

UAG is a one of the stop codons.

The genetic code is the set of rules for translating the information contained in the genome of living cells in order to synthesize proteins. In a broad sense, it establishes the correspondence between the genotype and the phenotype of an organism. This code is based in particular on the correspondence between, on the one hand, the nucleotide triplets, called codons, on the messenger RNA and, on the other hand, the proteinigenic amino acids incorporated in the proteins synthesized during the translation phase of messenger RNA by ribosomes.
