New discovery shows human cells can write RNA sequences into DNA

Scienmag

In a discovery that challenges long-held dogma in biology, researchers show that mammalian cells can convert RNA sequences back into DNA, a feat more common in viruses than eukaryotic cells PHILADELPHIA – Cells contain machinery that duplicates DNA into a new set that goes into a newly formed cell.

Why Proviral DNA Drug Resistance Testing is Useful in Guiding Treatment Decisions for HIV-1 Patients

XTalks

Compared to standard plasma HIV-1 RNA drug resistance profiling, which requires a viral load of at least 500 copies per mL, proviral HIV-1 testing can be performed on samples with much lower virion counts of <50 copies per mL (below the detectable limit in RNA testing). Proviral DNA Genotyping. HIV Drug Resistance Testing.

New CRISPR-Based Rapid COVID-19 Test Can Detect SARS-CoV-2 Variants

XTalks

Moreover, studies show that saliva samples can contain a marginally higher SARS-CoV-2 viral load compared with nasopharyngeal samples (shown in a study involving hospitalized patients), and that the virus can be detected in saliva for a greater number of days post-infection. A porous membrane was engineered to capture RNA on its surface.
