Web24 sep. 2008 · "Molecular homology" is defined in the glossary as "similarity of the nucleotide sequences of DNA or RNA molecules, or the amino acid sequences of proteins." In the text of this chapter, homology is never explicitly defined, but is referred to in the context of "similarities," without any restrictions regarding function. The term "percent homology" is often used to mean "sequence similarity”, that is the percentage of identical residues (percent identity), or the percentage of residues conserved with similar physicochemical properties (percent similarity), e.g. leucine and isoleucine, is usually used to "quantify the homology." Based on the definition of homology specified above this terminology is incorrect since s…
