NEET Botany Molecular Basis of Inheritance Questions Solved

NEET - 2017

If there are 999 bases in an RNA that codes for a protein with 333 amino acids and the base at position 901 is deleted such that the length of teh RNA becomes 998 bases, how many codons will be altered?

(1) 1

(2) 11

(3) 33

(4) 333

(3) 33 codons will be altered if the 901st base is deleted and RNA has only 998 bases instead of 999 bases.

Total bases present in RNA = 999

Bases left after deletion of 901st base in RNA = 999 - 901 = 98

Number of codon present in 98 = 33

(Approximately as three codons code for one amino acid).
