13. Write the amino acid chain for the following DNA sequence: AGTCGCTATTAGCCG
a. Serine-Alanine-Isoleucine-Isoleucin e-Glycine
b. Serine-Arginine-Cysteine-Stop
c. Arginine-Leucine-Isoleucine-Alanine -Threonine
d. Alanine-Valine-Cysteine-Arginie-Thr eonine

a. Serine-Alanine-Isoleucine-Isoleucine-Glycine

Explanation:

This question is describing gene expression, which comprises of transcription and translation. Transcription is the process by which a DNA molecule is used as a template to synthesize a mRNA molecule while in translation, the mRNA is used to synthesize an amino acid sequence using a set of three nucleotide bases called CODON in the mRNA.

According to this question, the following DNA sequence is given: AGTCGCTATTAGCCG. The process of transcription will form the following mRNA sequence from this DNA sequence: UCAGCGAUAAUCGGC.

Translation will make use of the genetic code to produce the following amino acids. Note that, one codon e.g UCA encodes an amino acid (serine).

The amino acid sequence is: Serine-Alanine-Isoleucine-Isoleucine-Glycine.

UCA codes for Serine

GCG codes for Alanine

AUA codes for Isoleucine

AUC codes for Isoleucine

GGC codes for Glycine
