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).

Researchers unveil protection mechanism of telomeres from DNA repair

In the latest issue of the journal Nature, Miguel Godinho Ferreira, Principal Investigator at the Instituto Gulbenkian de Ciência (IGC) in Portugal, lead a team of researchers to shed light on a paradox that has puzzled biologists since the discovery of telomeres, the protective tips of chromosomes: while broken chromosome ends generated by DNA damage (such as radiation or cigarette smoke) are quickly joined together, telomeres are never tied to each other, thus allowing for the correct segregation of the genetic material into all cells in our body.

Researchers reveal surface protein alteration mechanism of mycoplasma bacteria

Pathogenic bacteria have evolved a variety of mechanisms to avoid being killed by the immune systems of the humans and animals they invade. Among the most sophisticated is that practised by mycoplasmas, which regularly change their surface proteins to confuse the immune system. Recent work in the group of Renate Rosengarten and Rohini Chopra-Dewasthaly at the University of Veterinary Medicine, Vienna has revealed surprising new details of the way they do so and at the same time raised important evolutionary questions.
