Study shows the microRNA miR-19 helps budding adult brain cells stay on track - A small stretch of ribonucleic acid called microRNA could make the difference between a healthy adult brain and one that’s prone to disorders including schizophrenia. Scientists at the Salk Institute discovered that miR-19 guides the placement of new neurons in the adult brain, and the molecule is … [Read more...] about Small molecule keeps new adult neurons from straying, may be tied to schizophrenia
Although most DNA is packaged in chromosomes within the nucleus, mitochondria also have a small amount of their own DNA. This genetic material is known as mitochondrial DNA or mtDNA. Mitochondria are structures within cells that convert the energy from food into a form that cells can use. Each cell contains hundreds to thousands of mitochondria, which are located in the … [Read more...] about What is Mitochondrial DNA?
