advanced and accurate method used when very precise identification is required. We can classify bacteria into sub-species, strains, serotypes, or pathovar levels using molecular methods. This method includesPolymerase Chain Reactions (PCR), DNA / RNA probe tests, Microarray, Electrophoresis, Proteomics...
The Purine-Rich Binding Protein A (Pur-α) is a multifunctional RNA-binding protein that plays a key role in gene transcriptional regulation and is involved in brain development, synaptic plasticity, and memory retention [29]. Barbe et al. found that mice with Pur-α heterozygosity exhibit memo...
What are the 6 enzymes involved in DNA replication? Enzymes involved in DNA replication are: Helicase (unwinds the DNA double helix) Gyrase (relieves the buildup of torque during unwinding) Primase (lays down RNA primers) DNA polymerase III (main DNA synthesis enzyme) DNA polymerase I (replac...
Interestingly, the RNA transcriptional machinery has a constraining role for local chromatin motion in the cell (Figure 2f) [67,70,95]. Knockdown of RNA polymerase II (RNAPII) or other transcription regulatory factors, as well as RNAPII inhibitor treatments, released RNAPII from chromatin and raise...
What is a DNA polymerase? What does it do or what is it involved in? The polymerase cannot start a new DNA strand on its own. What must be present before this enzyme can perform its primary function? During a polymerase chain reaction, what part of the process indicates the marking or ...
