A Framework for Orthology Assignment from Gene Rearrangement Data,omes have the same gene content and that no gene is duplicated. While these assumptions allow one to work with organellar genomes, they are too restrictive for nuclear genomes. The main challenge in handling more realistic data is how to deal with gene families, specifically, how to identify ortholo作者: 個(gè)阿姨勾引你 時(shí)間: 2025-3-23 21:36
