gene (redirected from H gene)

gene  (jn)

n.

A hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes.

[German Gen, from gen-, begetting, in Greek words (such as genos, race, offspring); see gen- in Indo-European roots.]

Noun

a unit composed of DNA forming part of a chromosome, by which inherited characteristics are transmitted from parent to offspring [German Gen]

gene  (jn)

A segment of DNA, occupying a specific place on a chromosome, that is the basic unit of heredity. Genes act by directing the production of RNA, which determines the synthesis of proteins that make up living matter and are the catalysts of all cellular processes. The proteins that are determined by genetic DNA result in specific physical traits, such as the shape of a plant leaf, the coloration of an animal's coat, or the texture of a person's hair. Different forms of genes, called alleles, determine how these traits are expressed in a given individual. Humans are thought to have about 35,000 genes, while bacteria have between 500 and 6,000.

gene - (genetics) a segment of DNA that is involved in producing a polypeptide chain; it can include regions preceding and following the coding DNA as well as introns between the exons; it is considered a unit of heredity; "genes were formerly called factors" cistron, factor dominant gene - gene that produces the same phenotype in the organism whether or not its allele identical; "the dominant gene for brown eyes" allele, allelomorph - (genetics) either of a pair (or series) of alternative forms of a gene that can occupy the same locus on a particular chromosome and that control the same character; "some alleles are dominant over others" genetic marker - a specific gene that produces a recognizable trait and can be used in family or population studies homeotic gene - one the genes that are involved in embryologic development lethal gene - any gene that has an effect that causes the death of the organism at any stage of life linkage group, linked genes - any pair of genes that tend to be transmitted together; "the genes of Drosophila fall into four linkage groups" modifier gene, modifier - a gene that modifies the effect produced by another gene mutant gene - a gene that has changed so that the normal transmission and expression of a trait is affected nonallele - genes that are not competitors at the same locus operator gene - a gene that activates the production of messenger RNA by adjacent structural genes oncogene, transforming gene - a gene that disposes normal cells to change into cancerous tumor cells polygene - a gene that by itself has little effect on the phenotype but which can act together with others to produce observable variations proto-oncogene - a normal gene that has the potential to become an oncogene recessive gene - gene that produces its characteristic phenotype only when its allele is identical; "the recessive gene for blue eyes" regulator gene, regulatory gene - a gene that produces a repressor substance that inhibits an operator gene repressor gene - gene that prevents a nonallele from being transcribed structural gene - a gene that controls the production of a specific protein or peptide suppresser gene, suppressor gene, suppresser, suppressor - a gene that suppresses the phenotypic expression of another gene (especially of a mutant gene) transgene - an exogenous gene introduced into the genome of another organism X-linked gene - a gene located on an X chromosome holandric gene, Y-linked gene - a gene located on a Y chromosome chromosome - a threadlike strand of DNA in the cell nucleus that carries the genes in a linear order; "humans have 22 chromosome pairs plus two sex chromosomes" genetic science, genetics - the branch of biology that studies heredity and variation in organisms molecular biology - the branch of biology that studies the structure and activity of macromolecules essential to life (and especially with their genetic role) sequence - serial arrangement in which things follow in logical order or a recurrent pattern; "the sequence of names was alphabetical"; "he invented a technique to determine the sequence of base pairs in DNA" deoxyribonucleic acid, desoxyribonucleic acid, DNA - (biochemistry) a long linear polymer found in the nucleus of a cell and formed from nucleotides and shaped like a double helix; associated with the transmission of genetic information; "DNA is the king of molecules"
