A new life form discovered on a distant planet has a genetic code cons

1.	A new life form discovered on a distant planet has a genetic code consisting of five unique nucleotides and only one stop codon. If each codon has four bases, what is the maximum number of unique amino acids this life form can use ?(A) 624(B) 20(C) 124(D) 3124
Answer» Correct option (A) 624 Explanation: No. of unique nucleotide = 5 No. of bases in codon = 4 so, total combinations ⇒ 54 ⇒ 625 No. of stop codons = 1 so, unique amino acids (maximum) = 625 – 1 ⇒ 624

Answer»

Correct option (A) 624

Explanation:

No. of unique nucleotide = 5

No. of bases in codon = 4

so, total combinations ⇒ 54 ⇒ 625

No. of stop codons = 1

so, unique amino acids (maximum) = 625 – 1

⇒ 624
