A certain genetic disorder is caused by a mutation in the gene encoding a structural membrane protein. The faulty allele has a deletion of 12 nucleotides, resulting in a mutated coding sequence of 1848 nucleotides.
Assuming all nucleotides in this coding sequence directly code for amino acids using a triplet code (3 nucleotides per amino acid):
Calculate the number of amino acids found in the healthy, unaffected protein.
