homologous genes

homologous genes

Genes from organisms of different species that code for the same enzyme or other product. Homologous genes need not have the same base sequences.

Although these mycobacteria are considered nonpathogenic, they have homologous genes to mammalian cell entry that encode proteins involved in virulence and cell invasion.
This hinders the use of specific CNV-detection methods as first-tier tests for highly homologous genes. Alternatively, affordable and scalable nonspecific assays can potentially be used as "screening" tools such that only seemingly positive cases are followed up on.
They all harbor homologous genes including 3 trbs and 18 tras encoding a type IV F conjugative transfer system, 11 pils encoding a type IV pilus system, mobABC encoding a mobilization protein, and umuCD for DNA error-prone repair.
Worms have many more homologous genes that constitute gene families related to human genes, which share sequence similarities but may not have the same functions.
Our analysis showed that of the 16 pseudogenes pose highly stable mRNA structures, suggesting that these genes might be regulators of other homologous genes in the Salmonella.
5A), these results showed that the founction of homologous genes encoding the same protein are not the same.
Molecular testing has shown that the Rh-locus of human genome, which is located on the short arm of chromosome 1 (1 p36.2-p34), consists of two closely related and structurally homologous genes, RHD and RHCE.
Are Metazoan Rhodopsins and Microbial Rhodopsins Homologous Genes? The main purpose of this study is to answer the question: are metazoan rhodopsins and microbial rhodopsins homologous genes?
Although spv homologous genes on [pR.sub.ST98] were identified, the mechanism of [pR.sub.ST98] enhancing its host virulence was still not fully elucidated.
Users can also explore bovine disease genes based on comparative mapping of homologous genes and make searches centered on genes within user-selected quantitative trait loci (QTL) regions.
Nowadays, the most reliable criteria no longer are morphological, but molecular characteristics--for instance, number of base exchanges in homologous genes. One reliable approach of molecular phylogeny compares DNA sequences of genes that are present in all animals--in particular, gene segments that do not code for proteins.
We have identified Oxs1 homologous genes so far in rice, maize, Arabidopsis, fruit flies, mouse and human.
