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.

Answer 2

Amino acids are the building blocks of proteins. The amino acid is found in the set of three, known as codons.

Codons are extensively used in the transcription and translation of genetic sequences.

The given sequence of DNA: TAC GCG AAT ATC, will be decoded into:

Option B: START – Arginine – Leucine – STOP

mRNA is one of the types of RNA, which transcribes the information coded in the DNA. The decoding of the DNA sequence will be AUC - CGC - UUA - UAG.

• The AUC is a start codon, which is also known as isoleucine.
• The UAG is the stop codon, which is known as amber.
• UAA codes for leucine.
• CGC codes for arginine.

The codons are the sequence of amino acids in the set of three. These codons are made from the purines and pyrimidines.

The guanine will bind to cytosine, and adenine will be decoded into thymine or uracil in RNA. Thus, the decoding of RNA involves the conversion of purine to pyrimidine, and pyrimidine to purine.

Therefore, the correct decoded sequence of DNA: TAC GCG AAT ATC, will be START – Arginine – Leucine – STOP.
