The Gene Norman GroupGene Gene Sequence of DNA that determines traits in an organism This article is about sequences of DNA or RNA that code for functional molecules. For other uses, see Gene (disambiguation). In biology, the word gene has two meanings. The Mendelian gene is a basic unit of heredity. The molecular gene is a sequence of nucleotides in DNA that is transcribed to produce RNA. There are two types of molecular genes: protein-coding genes and non-coding genes.[1][2] During gene expression (the synthesis of RNA or protein from a gene), DNA is first copied into RNA. RNA can be directly functional or be the intermediate template for the synthesis of a protein. Chromosome (107 - 1010 bp) DNA Gene (103 - 106… (Source: Wikipedia)
