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

Answer:
33 codons will be altered.
Explanation:
We know that 3 bases form one amino acid. This combination of 3 bases i called a codon. Therefore, we can say a codon is made up of 3 bases and one codon forms one amino acid.
Here, there are 999 codons.
They will form 333 amino acids ( 3 bases for 1 codon)
Bases are present in a series and codons are formed in accordance with that series.
When one of the base is deleted and changed tha whole series following the base gets disrupted.
In this situation, base 901 is deleted. That means, all the codons following 901 base will get disrupted. But codons before 901 base will be alright and will form a normal amino acid.
900 bases will give - 900/3 = 300 amino acids.
300 codons are unaltered
altered codons = 999 - 900 = 99
99/3 = 33
Therefore, 33 codons will be altered.
