Chemical Analysis of DNA Damage

Analysis of chromatin integrity and DNA damage of buffalo spermatozoa

This study was conducted to determine chromatin integrity and DNA damage by DNA electrophoresis and comet assays of buffalo fresh and frozen semen. Semen samples were collected from four buffalo bulls and evaluated after freezing for semen motility, viability, sperm abnormalities, chromatin integrity and DNA damage. A significant variation was found in semen parameters after thawing. Highly sig...

DNA Chemical Damage and Its Detected

The DNA chemical damage is a very important researching project in chemistry, life science and related fields. In this paper, the biological function of DNA damage, the reason causing damage and the detecting technology of DNA damage are summarized and discussed.

Radiation track and DNA damage

Chemical investigation of light induced DNA bipyrimidine damage and repair.

In all organisms, genetic information is stored in DNA and RNA. Both of these macromolecules are damaged by many exogenous and endogenous events, with UV irradiation being one of the major sources of damage. The major photolesions formed are the cyclobutane pyrimidine dimers (CPD), pyrimidine-pyrimidone-(6-4)-photoproducts, Dewar valence isomers and, for dehydrated spore DNA, 5-(α-thyminyl)-5,6...
