Question

100 nucleotide long mrna with stop codon included at the end of the sequence, how many amino acids it may code for?

Answer 1

Explanation:

Each group of three nucleotides encodes one amino acid. Since there are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases).
