Notice that the first amino acid in the hbb protein starts with a valine (val) instead of a methionine (met). what is the most likely explanation for this based on what we have discussed about gene expression?
(a) blood cells have a completely different way of starting translation in all their genes.
(b) the messenger rna for hbb carries a mutation in the start codon.
(c) the start codon for the gene is one of the codons for valine (i. e. gua, guc, gug or guu).
(d) the protein that is first made gets modified afterwards
