DNA (deoxyribonucleic acid), the molecular "blueprint" carrying the genetic instructions that influence the growth, ...

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.

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.

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 ...

While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means ...

His team set about using cryo-EM to examine how RNAP remains clamped to DNA after transcription termination, and how RapA interacts with it. They chose negatively supercoiled DNA—an underwound ...

Three new DNA markers have been developed to allow sizing and quantitation of linear and supercoiled, double-stranded DNA. The Kb DNA Ladder contains 15 linear fragments from 250 bp to 12 kb. Bands ...
