In 125 amino acid sequence if the \(25^{\text {th }}\) codon for amino acid is mutated to UAA, then:
1 A polypeptide of 124 amino acids is formed
2 A polypeptide of 25 amino acids is formed
3 A polypeptide of 24 amino acids is formed
4 No polypepetides are formed
Explanation:
UAA is one of the three stop codons which do not code for any amino acid. If the codon for \(25^{\text {th }}\) amino acid is mutated to UAA then the polypeptide chain will be terminated at that point because tRNA cannot bring next amino acid as UAA is termination codon. So, in this case a polypeptide chain of 24 amino acids will be formed.

Which of the following features of genetic code does allow bacteria to produce human insulin by recombinant DNA technology?
1 Genetic code is not ambiguous
2 Genetic code is redundant
3 Genetic code is nearly universal
4 Genetic code is specific
Explanation:
In recombinant DNA technology bacteria is able to produce human insulin because genetic code is nearly universal.

Statement A : The codon 'AUG' codes for methionine and phenylalanine. Statement B : 'AAA' and 'AAG' both codons code for the amino acid lysine. In the light of the above statements, choose the correct answer from the options given below.
1 Both Statement I and Statement II are true
2 Both Statement I and Statement II are false
3 Statement I is correct but Statement II is false
4 Statement I is incorrect but Statement II is true
Explanation:
AUG codes for methionine whereas AAA & AAG will code for lysine

The one aspect which is not a salient feature of genetic code, is its being
1 Ambiguous
2 Specific
3 Degenerate
4 Universal
Explanation:
The salient features of genetic code includes: triplet in nature, universal, non overlapping, degenerate, comma less, nonambiguous or specific, initiator codon, nonsense or terminator codons. It does not include the characteristic ambiguous as each codon codes for only one amino acid that is why, it is specific in character.
