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 ...

RNA polymerase is an enzyme that is responsible ... there are striking similarities among transcriptional mechanisms. For example, all species require a mechanism by which transcription can ...

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 ...

Northwestern Medicine investigators have discovered a novel mechanism that recognizes and eliminates "bad" transcriptional ...
