RNA polymerases are sloppy. A retrovirus with an RNA genome, which is copied into DNA by a reverse transcriptase, is prone to mutations because the enzyme lacks the 3’ to 5’ proofreading capability of ...

Switching to islatravir and doravirine was just as effective as bictegravir/emtricitabine/tenofovir alafenamide fumarate (BIC ...

Through laboratory techniques that track quantities of mRNA, scientists can identify which genes are “turned on” and which are “turned off” in an organism’s tissue at a given time, as ...

for HHC with central laboratory-confirmed SARS-CoV-2 negativity by reverse transcription polymerase chain reaction (RT-PCR).

It is an ester-derived prodrug that is converted in vivo by serum and tissue esterases to tenofovir, an acyclic nucleoside phosphonate (nucleotide) that inhibits HIV reverse transcriptase.

The company’s unique suite of optimized gene editors, which is capable of approaches ranging from gene knockout, excisions, reverse transcriptase editing, and large gene insertion, goes beyond the ...

Since the emergence of COVID-19 in late 2019, the gold standard in testing for the disease has been a nuclear-derived technique: real-time reverse transcription–polymerase chain reaction, or real-time ...

This is a process called ‘reverse transcription’. They do this because only DNA can be copied — or amplified — which is a key part of the real time RT–PCR process for detecting viruses. Scientists ...

Gene expression studies by quantitative reverse-transcription PCR (qRT-PCR) can be challenging when attempted with samples of a few cells or a single cell. Epicentre's Message BOOSTER ™ cDNA ...
