There are a variety of different types of RNA polymerases that can transcribe different types of RNA. RNA polymerase II, shown here, is responsible for creating messenger RNA (mRNA), which is the main ...
At this point, RNA polymerase begins moving down the DNA template strand in the 3' to 5' direction, and as it does so, it strings together complementary nucleotides. By virtue of complementary ...
Genetically speaking, it's a bacterium's worst-case scenario: During transcription, newly minted RNA sticks to its DNA template, forming a 3-stranded ... the RNA polymerase (RNAP) enzyme ...
Northwestern Medicine investigators have discovered a novel mechanism that recognizes and eliminates "bad" transcriptional ...
DNA transcription is the vital first step needed for switching on our genes. For a gene to be switched on, it must be acted ...
which in turn bind to regulatory sites in the DNA that effectively block RNA polymerase binding (Figure 3). The control of gene expression in eukaryotes is more complex than that in prokaryotes.
A global team has made a significant advance in understanding how bacterial plasmids contribute to antibiotic resistance.
TComparison of a single-stranded RNA and a double-stranded DNA with their corresponding nucleobases (Image: Wikimedia Commons, CC SA 3.0) The nucleotides are connected ... In this process, the enzyme ...
This unwinding of the helix is caused by an enzyme (helicase enzyme). The enzyme RNA polymerase attaches to the DNA in a non-coding region just before the gene. RNA polymerase moves along the DNA ...
