Genetic `barcode` to identify origin of malaria

Last Updated: Friday, June 13, 2014, 18:31

Containing malaria could be a lot more convenient as researchers have now designed a genetic barcode of malaria parasite, which can be used to identify the geographic origin of the parasite from a blood sample and monitor its spread.

Researchers have claimed that a molecule critical to stem cell function plays a major role in determining human hair color.

How DNA is `edited` to correct genetic diseases

Last Updated: Tuesday, May 27, 2014, 14:36

Researchers have taken a major step forward understanding how enzymes `edit` genes, which has paved the way for correcting genetic diseases in patients.

Faulty DNA-copying may lead to cancer

Last Updated: Tuesday, May 06, 2014, 18:08

Scientists have found that `fragile sites` that can be a breeding ground for human cancers appear in specific areas of the genome where the DNA-copying machinery is slowed or stalled.

International study gives new insights into development in womb

Last Updated: Tuesday, May 06, 2014, 15:04

An international study, involving scientists at the University of Southampton, has used an analysis of epigenetic marks on De-oxyribonucleic acid ( DNA) to measure how much a baby`s development in the womb is determined by the genes inherited from the parents, as compared with the mother`s nutrition, mental health and lifestyle.

New hope for breast cancer sufferers

Last Updated: Sunday, May 04, 2014, 13:39

Scientists have found that mice lacking one copy of a gene called CTCF have a normal DNA methylation and are markedly predisposed to cancer, which can provide new hope for breast cancer.
