Active genes. Labeling method extends ability to read DNA modificationResearchers at Emory University School of Medicine and the University of Chicago have developed a method for the identification and association with a sixth nucleotide, whose biological role scientists are only now beginning to to explore.
‘.. The method is described in Nature Biotechnology onlin.process, the researchers were able for the first time, see how 5-hydroxymethylcytosine distributed across the genome. In contrast to 5-methylcytosine , a chemical modification of DNA, which is generally found in genes that are turned off, this additional layer for from modification in active genes. 5-HMC seems frequently in embryonic stem cells and brain cells, as compared to other cell types, and their incidence increases substantially as the brain matures.The researchers Inspect more the interaction between the pheromone and to nerve cell receptors Smith said that when pheromone system operate in this way other.. Pheromones are molecules an organism an organism trigger certain behaviors other members of its species. Insect make only work the interaction between CVA is with some type of nerve cells called T1 into the antenna the Drosophila. Holes in the antenna permit a fluid-filled of Appeal CVA those neurons adress these nerve cells force.
