. 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?

A: 333

B: 1

C: 11

D: 33


Best Answer


Three RNA codes code for a single amino acid.

999 RNA codes for 333 amino acids.

If the base at 901 position is deleted, upto 900 bases will be normal and after 901th base there will be alteration.

999-900= 99 altered bases, as 3 bases codes for 1 amino acid, so 99 bases will code for 33 amino acids.


Correct Option is: (D) 33
