A gene family is a set of several similar genes, formed by duplication of a single original gene, and generally with similar biochemical functions. One such family are the genes for human hemoglobin subunits; the ten genes are in two clusters on different chromosomes, called the α-globin and β-globin loci. These two gene clusters are thought to have arisen as a result of a precursor gene being dupli… WebJan 19, 2007 · A gene cluster is defined as a group of genes that are annotated with the same GO term or have the same parent term, and are also found within close proximity to each other on a chromosome. Cluster size refers to the number of genes in the cluster having the same GO term or parent term.

WebTogether, these eight genes encode almost all the steps in the pathway for catabolism of extracellular melibiose (a disaccharide of galactose and glucose). We show that a progenitor 5-gene cluster containing GAL 7-1-10-4-2 was likely present in the common ancestor of Torulaspora and Zygotorulaspora.

WebFeb 6, 2013 · By genomic sequence analysis, Marzluff et al. (2002) determined that the histone gene cluster on chromosome 1q21, which they called histone gene cluster-2 (HIST2), contains 6 histone genes, including HIST2H3C. The cluster also contains 2 H3 pseudogenes, designated HIST2H3A and HIST2H3B.
