Concept explainers
(a)
Interpretation: The dipeptide that is formed by transcription of the given DNA segment has to be predicted.
Concept introduction: DNA stands for deoxyribonucleic acid, is a biological macromolecule. DNA contains double helical strands along with the complementary base pairs. The four complementary bases of DNA are adenine, thymine, guanine and cytosine.
A compound possessing two amino acids joined together by one peptide bond is known as dipeptide. The amino acids present in the dipeptide are linked via peptide linkages.

Answer to Problem 11.138EP
The dipeptide that is formed by transcription of the given DNA segment is
Explanation of Solution
The given DNA base sequence is,
The transcription of the above given DNA sequence forms the new hnRNA segment which is given as,
The amino acid that specifies the first codon,
The amino acid that specifies the second codon,
Thus, the amino acid sequence or dipeptide that is formed by transcription of the given DNA segment is
(b)
Interpretation: The dipeptide that is formed if a point mutation converts

(b)
Answer to Problem 11.138EP
The dipeptide that is formed if a point mutation converts
Explanation of Solution
The given DNA base sequence is,
If point mutation occurs in the given DNA base sequence and converts
The new codon formed after the base pairing is given as,
The amino acid that specifies the first codon,
The amino acid that specifies the second codon,
Thus, the amino acid sequence or dipeptide that is formed after the point mutation of the given DNA segment is
(c)
Interpretation: The dipeptide that is formed if a point mutation converts
Concept introduction: DNA stands for deoxyribonucleic acid, is a biological macromolecule. DNA contains double helical strands along with the complementary base pairs. The four complementary bases of DNA are adenine, thymine, guanine and cytosine.
The process of permanently changing the nucleotide sequence of a genome of any organism is known as mutation. In point mutation, one base is replaced by another base in the given base pair sequence.

The given DNA base sequence is,
If point mutation occurs in the given DNA base sequence and converts
The new codon formed after the base pairing is given as,
The amino acid that specifies the first codon,
The amino acid that specifies the second codon,
Thus, the amino acid sequence or dipeptide that is formed after the point mutation of the given DNA segment is
