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 the RNA becomes 998 bases, how many codons will be altered?NEET 2017

Answer:
C
Solution:
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
3 codon= 1 amino acid
Therefore 98/3= approx 33
A number of codons present in 98 bases= 33 (Approximately as three codons code for one amino acid).
