the primary structure of human apolipoprotein ( apo ) b-48 has been deduced and shown by a combination of dna excess hybridization , sequencing of tryptic peptides , cloned complementary dnas , and intestinal messenger rnas ( mrnas ) to be the product of an intestinal mrna with an in-frame uaa stop codon resulting from a c to u change in the codon caa encoding gln2153 in apob-100 mrna .
