Each gene tells a cell to make a specific molecule, but this isn't performed by the DNA itself. Instead, the information is relayed to cellular machinery by a molecule called messenger RNA.

Gene regulation refers to the mechanisms that act to induce or repress the expression of a gene. These include structural and chemical changes to the genetic material, binding of proteins to ...

New work by Columbia researchers has turned a textbook principle of genetics on its head and revealed why some people who carry disease-causing genes experience no symptoms. Every biology student ...

The TP53 gene is a gene that is mutated in many cancers. It is the most common gene mutation found in cancer cells. A tumor-suppressor gene, TP53 codes for a protein that inhibits the development and ...

Gene expression is the generation of a functional gene product from the information encoded by a gene, through the processes of transcription and translation. Gene products are often proteins ...

Some genes are beneficial and enhance longevity. For example, the gene that helps a person metabolize cholesterol would reduce a person's risk of heart disease. Some gene mutations are inherited.
