Consider the following mRNA base sequence
- a. What dipeptide is coded for by this mRNA?
- b. What dipeptide is formed if a point mutation converts CAC to AAC?
- c. What dipeptide is formed if a point mutation converts ACC to ACU?
- d. What dipeptide is formed if a point mutation converts CAC to AAC and ACC to ACU?
(a)
Interpretation: The dipeptide that is coded by the given mRNA has to be predicted.
Concept introduction: Ribonucleic acid (RNA) is responsible for the synthesis of the molecules that carry out essential cellular functions.. RNA contains the complementary base pairs. The four complementary bases of RNA are adenine, uracil, 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 11.136EP
The dipeptide that is coded by the given mRNA is
Explanation of Solution
The given mRNA base sequence is,
The amino acid that specifies the base pair,
The amino acid that specifies the base pair,
Thus, the amino acid sequence or dipeptide for the given mRNA base sequence is
(b)
Interpretation: The dipeptide that is formed if a point mutation converts
Concept introduction: Ribonucleic acid (RNA) is responsible for the synthesis of the molecules that carry out essential cellular functions.. RNA contains the complementary base pairs. The four complementary bases of RNA are adenine, uracil, 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.
Answer to Problem 11.136EP
The dipeptide that is formed if a point mutation converts
Explanation of Solution
The given mRNA base sequence is,
If point mutation occurs in the given mRNA base sequence and converts
The amino acid that specifies the base pair,
The amino acid that specifies the base pair,
Thus, the amino acid sequence or dipeptide formed after the point mutation is
(c)
Interpretation: The dipeptide that is formed if a point mutation converts
