71mating-type genes — Genes that, in Saccharomyces cerevisiae, specify into which of the two mating types (a and a S a particular cell falls. Only unlike mating type haploids will fuse. The interest derives from the way in which mating type is switched: the existing… …
72paralogous genes — Genes that result from duplication of existing genes and then divergence of function contrast with orthologous genes …
73modifer genes — Genes that affect the phenotypic expression of genes at other loci …
74sex-linked genes — Genes in the sex chromosomes, linked in heredity to the genes determining sex …
75orthologous genes — Genes related by common phylogenetic descent contrast with paralogous genes …
76pol genes — Genes coding for DNA polymerases of which there are three in E. coli, polA, polB, and polC coding for polymerases I, II, and III respectively. Pol genes in oncogenic retroviruses code for reverse transcriptase …
77orthologous genes — genes in different species that are similar in DNA sequence and encode proteins having the same function; they originate from a single ancestral gene that diverged after speciation, e.g., the genes encoding β globin chains in different… …
78paralogous genes — genes in a single species that have similar DNA sequences and encode proteins with similar or related functions; they are likely to have originated from a single ancestral gene, diverging after duplication, e.g., the genes encoding α and… …
79housekeeping genes — Genes that code for proteins or RNAs that are important for all cells and are thus constitutively active. Term used by contrast with ‘luxury’ proteins, those that are only produced by differentiated cells …
80PAS genes — Genes essential for the biogenesis and proliferation of peroxisomes in yeast ( S. cerevisiae ). PAS1 codes for a rather hydrophilic 117 kD protein with two ATP binding sites and similarity with some ATPases, PAS2 codes for a 183 residue… …
