Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If a gene has 30 nucleotides, how many amino acids does it have?
A
3
B
10
C
60
D
90
Explanation: 

Detailed explanation-1: -So hence the answer to the question is 10 amino acids in turn can be generated using these 30 nucleotide gene sequence it.

Detailed explanation-2: -Answer and Explanation: The correct answer is (c): three. The mRNA templates contain the code for proteins as nucleotide triplets called codons. Each triplet universally corresponds to a specific amino acid.

Detailed explanation-3: -Thirty nucleotides are there in an mRNA. One codon consist of three nucleotides and one codon can code one amino acid but one amino acid can be coded by more than one codon. Therefore maximum 10 amino acids can be coded by 10 codon or 30 nucleotides if each codon codes a different amino acid.

Detailed explanation-4: -A. 1. Three is the minimum number of nucleotides per codon needed to encode 20 amino acids.

Detailed explanation-5: -Answer and Explanation: Transcription and translation of a gene that has 30 coding nucleotides would form a protein that has no more than 10 amino acids.
