Oct 2015 Molecular Homology Gets A New Definition

A much needed framework for assessing molecular homology is now published. The paper, by David Morrison, Matt Morgan, and Scot Kelchner, synthesizes nearly three decades of ideas about the nature of homology at the nucleotide, gene, and protein levels. Our new definitions could help improve the automated alignment of DNA sequences and the evolutionary analysis of genomic data. Or it might not. We'll see!
