The chapter "Sequence Analysis" from the National Cancer Institute's NCI Thesaurus (Code C17565) defines sequence analysis as the determination of the order of component residues in macromolecules, such as amino acids in proteins or nucleotide bases in DNA/RNA. It also includes computational methods used to compare the similarities between nonidentical proteins or molecules of DNA or RNA.The chapter "Sequence Analysis" from the National Cancer Institute's NCI Thesaurus (Code C17565) defines sequence analysis as the determination of the order of component residues in macromolecules, such as amino acids in proteins or nucleotide bases in DNA/RNA.
