Retroviral reverse transcriptases contain a DNA polymerase activity that can copy an RNA or DNA template and an RNase H activity that degrades the viral RNA genome during reverse transcription. RNase H makes both specific and nonspecific cleavages; specific cleavages are used to generate and remove

HIV-1 reverse transcriptase-associated RNase H cleaves RNA/RNA in arrested complexes: implications for the mechanism by which RNase H discriminates between RNA/RNA and RNA/DNA.

Sen. Tom Cotton (R-Ark.) recently faced blowback for his remarks suggesting China may collect the DNA of U.S athletes who participate in the upcoming Winter Olympics. "In 2022, thousands of world-class athletes will gather to compete in China," The Arkansas senator said. "Their DNA will present a.....

Modern Egyptians have more DNA from sub-Saharan Africa than mummies entombed in their country, according to the first genome data on mummies. The findings are h

Currently available COVID-19 vaccines rely on mRNA strands to teach the human immune system to recognize the SARS-CoV-2 virus. Now, researchers reporting in PLOS Neglected Tropical Diseases have reported the successful development of a vaccine that instead uses DNA encoding the virus' spike protein.

Researchers believe information on DNA repair could potentially form the basis for understanding how cells respond to chemotherapy and radiation and potentially even lead to improved cancer treatments.

DNA sequences that can fold into shapes other than the classic double helix tend to have higher mutation rates than other regions in the human genome and are major contributors to regional variation in mutation rates in the genome.

My grandmother developed Parkinson's disease after she turned 70, so I was going to go online and get one of those DNA testing kits to see if I was at a heightened risk of getting it too. What do you docs think? Thaleesa B., Denver Well, there's genetic testing and there's genetic testing. If you a...
