DNA - Isolation & purification
Research News and Information
Definition of 'DNA'A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine). |

Citrulline as a marker for chemotherapy induced mucosal barrier injury in pediatric patients.
13 Dec 2009 
BACKGROUND: The currently used National Cancer Institute (NCI) adverse events criteria for mucosal barrier injury (MBI) are insufficient for use in children. We searched for objective, easily measurable indicators for MBI in children with cancer. ... Read more...
Effect of adipose tissue on the sexual dimorphism in metabolic flexibility.
30 Oct 2009 Metabolic flexibility is the ability to transition between fat oxidation (fasting state) and glucose oxidation (fed state). We hypothesized that adipose tissue inflammation and lipid metabolism contribute to sexual dimorphism in metabolic ... Read more...
25 Oct 2009 A hitherto undescribed satellite DNA family (AvaII satDNA) has been isolated and characterised in Eumeces schneideri, a squamate reptile belonging to the family Scincidae. AvaII satDNA is characterised by a monomer length of 208 bp, a GC content of ... Read more...
