Webgene, unit of hereditary information that occupies a fixed position (locus) on a chromosome. Genes achieve their effects by directing the synthesis of proteins. In eukaryotes (such as animals, plants, and fungi), genes are contained within the cell nucleus.

The hereditary material i.e. DNA (deoxyribonucleic acid) of an organism is composed of a sequence of four nucleotides in a specific pattern, which encodes information as a function of their order. Genomic organization refers to the linear order of DNA elements and their division into chromosomes. "Genome organization" can also refer to the 3D structure of chromosomes and the positi…
