The genome sustains so much wear and tear, much of it hardly noticeable, that even the small portion of DNA damage that stays unrepaired far exceeds our inventory-taking abilities. Taking stock of DNA ...

Molecular biologists, including the forensic investigators on the popular TV show CSI, use gel electrophoresis to separate DNA fragments from each other in order to analyze the DNA. A team of ...

A team of scientists has found that ovarian cancer could be identified up to a year in advance thanks to a new method of spotting DNA patterns in blood samples. The rest of this article is behind a ...

Could it be that one of only three known markers directly targeting the DNA does not exist outside the realm of microbes? Now, researchers led by Xiaoqi Feng at the Institute of Science and Technology ...

Helsinki, 4 July 2016: Despite the claims and counter-claims for new embryo assessment techniques introduced over the past two decades, the search for the holy grail of assisted reproduction - the key ...

The fall armyworm, Spodoptera frugiperda (J. E. Smith), includes morphologically indistinguishable corn and rice strains. The two strains were surveyed for diagnostic restriction patterns in ...
