An enzyme isolated from rat heart has 261 amino acid residues and is encoded by a gene with 1305 bp. What is the relationship between the number of amino acid residues in the enzyme and the number of nucleotide pairs i its gene? The 1305 bp gene encodes the 261 amino acid enzyme and another enzyme that is 174 bp. The 261 amino acids are encoded within introns spanning 783 bp of the gene's transcript. The entire 1305 bp gene codes for amino acids in the enzyme. Five nucleotides code for a single amino acid. The 261 amino acids are encoded by 783 bp. The remaining 522 bp in the sequence are not translated.
