If there are 999 bases in 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

A

1

B

11

C

33

D

333

Text Solution

Verified by Experts

The correct Answer is:
C
33 condons will be altered if the 901 1st base is deleted and RNA has only 998 bases instead of 999 bases. Total bases presents in RNA = 999 Bases left after deletion of 901 st base in RNA =999-901 =98 Number of codon present in 98 =33 (Approximately as three codens code for one amino acid).
