Gen Small

A small gene is a certain range of genes on a chromosome that affects genes located in one cell. The main advantage of small genes is their brevity, which ensures simple information encoding and storage stability. They usually represent a single, functionally independent unit of genetic code that may include many known genes. In addition, small genes can be integrated or inherited from other sources into cells. Their function is to encode and regulate genetic processes.

For example, a gene for mitochondria, used only in cells, is an example of a small gene. It performs certain biological functions and contains specific information necessary for certain biochemical reactions to occur during cellular respiration. A small gene is an independent unit of larger genomes such as chromosomes. It typically encodes microRNAs, long noncoding RNAs, or other small RNA molecules that perform specific functions outside of its construct.

The functions of small range genes are little studied, but they play an important role in the regulation of cellular processes and the development of organisms. Small genes are especially useful for creating recombinant cells and vaccines.
