A new life from discovered on a distant planet has a genetic code consisting of five unique nucleotides and only one stop codon. If each has four bases, what is the maximum number of unique amino acids this life from can use?

A

624

B

20

C

124

D

3124

Text Solution

Verified by Experts

The correct Answer is:
A
No. of unique nucleotide =5
N0. of bases in codon = 4
So, total combiations `rArr5^(4)rArr625`
No. of stop condons =1
so, unique amino acids (maximum ) `=625-1rArr624`
