If a protein will end up with 30 amino acids, how many codons, not including the STOP codon, were on the mRNA transcript that produced it?

30 codons

Explanation:

Translation is the second process of gene expression, which involves the synthesis of amino acid sequence from mRNA. This process occurs in the ribosome where the mRNA is read in a group of three nucleotide bases called CODON. Each codon specifies a particular amino acid.

Since one codon specifies or translates into one amino acid, a protein with 30 amino acids will contain 30 codons (exclusive of STOP CODONS) on the mRNA transcript.

this would be a math

i don’t no. suiopgohjk
