Cistron

A gene is a locatable region of genomic sequence, corresponding to a unit of inheritance, which is associated with regulatory regions, transcribed regions and/or other functional sequence regions. The physical development and phenotype of organisms can be thought of as a product of genes interacting with each other and with the environment, and genes can be considered as units of inheritance. A concise definition of gene taking into account complex patterns of regulation and transcription, genic conservation and non-coding RNA genes, has been proposed by Gerstein et al. "A gene is a union of genomic sequences encoding a coherent set of potentially overlapping functional products".

Noun
1. (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"
(synonym) gene, factor
(hypernym) sequence
(hyponym) dominant gene
(part-holonym) deoxyribonucleic acid, desoxyribonucleic acid, DNA
(classification) genetics, genetic science

A DNA segment coding for a specific polypeptide, and includes its own start and stop codons. When an mRNA encodes two or more proteins, it is called polycistronic.
