Definition Of Gene Homolog

Search the homologene database with the gene name.

Definition of gene homolog. Tpo gene name and human orgn. Definition one of a pair of chromosomes that segregate from one another during the first meiotic division. In biology homology is similarity due to shared ancestry between a pair of structures or genes in different taxa a common example of homologous structures is the forelimbs of vertebrates where the wings of bats and birds the arms of primates the front flippers of whales and the forelegs of four legged vertebrates like dogs and crocodiles are all derived from the same ancestral tetrapod. This elaborate tutorial provides an in depth review of the different steps of the biological production of protein starting from the gene up to the process of secretion.

Genes are expressed through the process of protein synthesis. If you know both the gene symbol and organism use a query such as this. One member of a chromosome pair. Homologue definition is something such as a chemical compound or a chromosome homologous.

The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches. The term homolog may apply to the relationship between genes separated by the event of speciation see ortholog or to the relationship betwen genes separated by the event of genetic duplication see paralog. 3a 6 meiotic unequal crossover results in the transfer of one rccx module from one chromosome to another and the location of the crossover point determines the composition of the resultant hybrid. If your search finds multiple records click on the desired record.

Either a speciation event orthologs or a duplication event paralogs or else a horizontal or lateral gene transfer event xenologs. A gene related to a second gene by descent from a common ancestral dna sequence. Genetic information and protein synthesis. Misalignment of homologous chromosomes during meiosis can also lead to unequal crossover resulting in large scale gene deletions.

Crossover can take place at the c4 cyp21 or tnx genes fig. Blast can be used to infer functional and evolutionary relationships between sequences as well as to help identify members of gene families. A gene similar in structure and evolutionary origin to a gene in another species. 8 people chose this as the best definition of homolog.
