HomoloGene, a tool of the United States National Center for Biotechnology Information (NCBI), is a system for automated detection of homologs (similarity attributable to descent from a common ancestor) among the annotated genes of several completely sequenced eukaryotic genomes. [1]
Homology (biology) The principle of homology: The biological relationships (shown by colours) of the bones in the forelimbs of vertebrates were used by Charles Darwin as an argument in favor of evolution. In biology, homology is similarity due to shared ancestry between a pair of structures or genes in different taxa.

Sciences. Biology. Homology (biology), any characteristic of biological organisms that is derived from a common ancestor. Sequence homology, biological homology between DNA, RNA, or protein sequences. Homologous chromosomes, chromosomes in a biological cell that pair up (synapse) during meiosis.
Homologous recombination is a type of genetic recombination in which genetic information is exchanged between two similar or identical molecules of double-stranded or single-stranded nucleic acids (usually DNA as in cellular organisms but may be also RNA in viruses ).
Sequence homology is the biological homology between DNA, RNA, or protein sequences, defined in terms of shared ancestry in the evolutionary history of life.
Homology modeling, also known as comparative modeling of protein, refers to constructing an atomic-resolution model of the " target " protein from its amino acid sequence and an experimental three-dimensional structure of a related homologous protein (the " template ").
Overview. Chromosomes are linear arrangements of condensed deoxyribonucleic acid (DNA) and histone proteins, which form a complex called chromatin. [2] . Homologous chromosomes are made up of chromosome pairs of approximately the same length, centromere position, and staining pattern, for genes with the same corresponding loci.
