Introduction to Genetics

... What is a gene? A gene is a unit of heredity that is passed down from parent to child. Genes are located on chromosomes that are in all of our cells, including the sperm and egg that make a baby. Genes are made of molecules or chemicals called DNA. The pattern of DNA will determine if the gene is wo ...

Minimal genome

The concept of minimal genome assumes that genomes can be reduced to a bare minimum, given that they contain many non-essential genes of limited or situational importance to the organism. Therefore, if a collection of all the essential genes were put together, a minimum genome could be created artificially in a stable environment. By adding more genes, the creation of an organism of desired properties is possible. The concept of minimal genome arose from the observations that many genes do not appear to be necessary for survival. In order to create a new organism a scientist must determine the minimal set of genes required for metabolism and replication. This can be achieved by experimental and computational analysis of the biochemical pathways needed to carry out basic metabolism and reproduction. A good model for a minimal genome is Mycoplasma genitalium, the organism with the smallest known genome. Most genes that are used by this organism are usually considered essential for survival; based on this concept a minimal set of 256 genes has been proposed.
