Four APOBEC3 proteins (A3D, A3F, A3G, and A3H) are known to restrict HIV-1 infection by catalyzing the deamination of cytosine in single-stranded DNA (ssDNA) into a uracil (red) during reverse ...

DNA polymerases carry out crucial functions in many DNA metabolic processes. Polymerases catalyse the addition, using a template, of complementary nucleotides to the 3′ end of DNA primer strands.

At least 250 million people worldwide are chronically infected with HBV, a small hepatotropic DNA virus that replicates through reverse transcription. Chronic infection greatly increases the risk for ...

Comparison of that ancient DNA with modern human DNA showed that the two species had interbred and that people today still carry the genetic fingerprint of that intermixing. Since then ...

Learning about your genetics and ancestry is easier than ever. All you need to do is choose from the many DNA ancestry tests available online, receive your kit and send back the required DNA samples.

Scientists at deCODE genetics have unveiled a groundbreaking map of human DNA mixing during reproduction, offering insights into genetic diversity, health, and fertility. Credit: SciTechDaily.com ...

DNA sequencing has now confirmed that the culprit was none other than an orca. The DNA evidence of the orca attack was found in the bite marks on the shark's carcass. (Ben Johnson, Portland Bait and ...

For decades, we’ve believed the bright redness of sunburn — along with its irritating sting and peeling skin — was the result of ultraviolet (UV) radiation wreaking havoc on DNA. But now ...

Cell-free methods reconstitute nuclease reaction on DNA or chromatin that are extracted from the cells to directly identify genomic cleavages in the test tubes. Representative cell-independent methods ...

The number of home DNA test kits offering nutrition and diet advice matched to your genes is growing. They’re based on the idea that each of us responds to foods differently, in part due to our ...

Of course, though, testing a child's parentage based on physical features is far too subjective — that's typically where DNA tests come in. Such tests can offer a far more scientific way of ...
