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 ...

The mammalian cortex, the region of the brain responsible for a wide range of higher-level cognitive functions, including sensory perception, motor control, and complex thought, is composed of a ...

Though almost every cell in your body contains a copy of each of your genes, only a small fraction of these genes will be expressed, or turned on. These activations are controlled by specialized ...

Learning which enhancers control which genes would prove valuable in developing new treatments for diseases with a genetic basis. Last year, the U.S. Food and Drug Administration approved the first ...

Scientists can now predict which single-letter changes to the DNA within our genomes will alter genetic instructions and disrupt development, leading to changes such as the growth of extra digits and ...

Genetic studies of diseases map segments of the genome driving disease. But to understand how those changes contribute to disease progression, it is important to understand how they may alter gene ...

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 ...

The DNA of plants and animals contains their blueprint. However, genes, the instructions for generating proteins, are found ...
