  • several
  • These very high rates might be due to the lack of proofreading function of the RNA-dependent RNA polymerase and have resulted in the emergence of several genetic variants of the virus. (wikipedia.org)
  • Covalent binding of the aglycone portions of several carboxylic acid (ester) glucuronides is known to occur to nucleophilic sites on serum albumin via transacylation reactions, for example. (wikipedia.org)
  • nucleotide
  • Many DNA polymerase contain an exonuclease domain, which acts in detecting base pair mismatches and further performs in the removal of the incorrect nucleotide to be replaced by the correct one. (wikipedia.org)
  • According to another study, when measured in a different solution, the DNA chain measured 22 to 26 ångströms wide (2.2 to 2.6 nanometres), and one nucleotide unit measured 3.3 Å (0.33 nm) long. (wikipedia.org)
  • activity
  • The role of telomeres and telomerase in cell aging and cancer was established by scientists at biotechnology company Geron with the cloning of the RNA and catalytic components of human telomerase and the development of a polymerase chain reaction (PCR) based assay for telomerase activity called the TRAP assay, which surveys telomerase activity in multiple types of cancer.

  • study
  • The plasma HIV-1 RNA polymerase chain reaction (PCR) assessments were planned at pre-Baseline (between 1 and 14 days prior to Day 1), up to Week 12 Follow- up of the Randomized Phase, up to Week 12 Follow-up of the Open Labeled Non-Randomized phase and every 6 months Follow-up of off study drug/on study phase, however the study was early terminated at Week 40.

  • approach
  • The one-step approach is thought to minimize experimental variation by containing all of the enzymatic reactions in a single environment. (wikipedia.org)
  • host
  • Infection is the invasion of an organism's body tissues by disease-causing agents, their multiplication, and the reaction of host tissues to the infectious agents and the toxins they produce. (wikipedia.org)
