The given nucleotide sequence on mRNA is as shown below:
5' AUGUCAUGGGAGUGAGUUGGGCUAAAAUAG 3'
(A) How many amino acids will be inserted in a polypeptide chain under normal conditions?
(B) How many amino acids will be inserted in a polypeptide chain in a mutated situation by the deletion of 9thnucleotide in the cistron part of DNA?
Options:
Answer:
B
Solution:
5'-AUG UCA UGG GAG UGA GUU GGG CUA AAA UAG-3'
Number of amino acids in normal condition=4(UGA is a stopping codon)
5'-AUG UCA UGG AGU GAG UUG GGC UAA AAU AG 3'
in the mutated situation (by deletion of 9th nucleotide in cistron part of DNA) = 7 (UAA is stop codon)
