If none of the nucleotides includes stop or start codons when a segment of a gene contains 27 nucleotides there will be 81 amino acids in this segment code.

Answer: Option B

<u>Explanation:</u>

Codon is a nucleotides within messenger RNA. A stop or start codon is a nucleotide triplet which signals protein termination. Start codons initiate to start translation while the stop codon initiates termination.

The genetic codes are the sequence for nucleotide that codes for amino acids. A segment containing 27 nucleotides multiplied by 3 gives 81 amino acids. Every nucleotide in an mRNA are read “three at a time”. Hence this segment codes for 81 amino acids.
