Read moreDNA and molecular biology has advanced by leaps and bounds. It has found use in pharmacology, genetic engineering in disease prevention, in increasing agricultural growth, in detection of disease and crime (forensics) etc. Some fields that have shown remarkable growth due to advances in DNA technology include: forensics bioinformatics pharmacology and nanotechnology archaeology and anthropometry…

Incubate with 2 units DNAse I at room temperature for 15 minutes. Add ammonium bicarbonate to the final concentration of 100mM, and then incubate with 2mU phosphodiesterase at 37oC in water bath for 2 hours. Add…
Read moreChinese researchers have determined the near-atomic structure of a protein crucial for repairing damaged DNA, an advance that may shed light on novel effective cancer therapies. Cells in our body continuously replicate to repair and replace damaged tissue, and each division requires a reprinting of the cell’s DNA. As the DNA duplicates, errors inevitably occur,…
