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 ...
During transcription, newly minted RNA sticks to its DNA template, forming a 3-stranded structure known as an R-loop. While ...
The process of transcription can be visualized by electron microscopy (Figure 1); in fact ... Three different types of RNA polymerase exist in eukaryotic cells, whereas bacteria have only one.
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 ...
