Organisms are made up of cells, and in each of those cells, a genome encodes the instructions for that organism to grow and survive. The human genome has at least 20,000 genes, and the expression of ...

DNA transcription is the vital first step needed for switching on our genes. For a gene to be switched on it must be acted upon by an enzyme called RNA polymerase. This is a molecular machine which ...

Researchers are investigating the role of non-coding DNA, or junk DNA, in regulating astrocytes, brain cells involved in ...

Every cell in our body contains the same DNA, yet liver cells are different from brain cells, and skin cells differ from muscle cells. What determines these differences? It all comes down to gene ...

The image on the right is both beautiful and exciting. Let me explain why. It's the paw of an embryonic mouse and a team of geneticists have inserted a fragment of human DNA into its cells. The ...

Research studying facial development in mice has given scientists new insights into the genetic controllers that determine the appearance of human faces. An international team of scientist identified ...

Scientists mapped hidden DNA switches in brain support cells to understand how gene control may influence Alzheimer’s disease ...

Helper T cells are kind of white blood cell that make up a large part of the immune system. They recognize pathogens and regulate the immune response. Many immune-mediated disease are caused by ...
