Noun
cistron - (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"
gene, factor
sequence film consisting of a succession of related shots that develop a given subject in a movie
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"
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)
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 an electrical device for suppressing unwanted currents
transgene an exogenous gene introduced into the genome of another organism
