DNA News and Research

RSS

DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

New research uncovers how superbug evades the immune system to cause infection

First extensive analysis of proteins in patients with acute lymphoblastic leukemia

The most common form of childhood cancer is acute lymphoblastic leukemia. Researchers at Lund University in Sweden, in cooperation with Karolinska Institutet, SciLifeLab and the University of Cambridge, have now carried out the most extensive analysis to date of ALL at the protein level, by studying the activity in over 8 000 genes and proteins.
