RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription. As complex molecule composed of protein subunits, RNA ...

This polymerase contains four catalytic subunits ... For example, researchers know that RNA pol II can bind to a DNA sequence within the promoter of many genes, known as the TATA box, to initiate ...

DNA polymerase enzymes facilitate this process, ensuring accurate copying of the genetic information. Transcription is the process by which the genetic information in DNA is copied into a ...

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

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 ...

Finally, DNA polymerase extends the primers ... enabling accurate quantification and gene expression analysis. RT-PCR is used to amplify RNA sequences by first converting RNA into complementary DNA ...

Enzymes called RNA polymerases transcribe DNA into RNA. RNA is the intermediary that carries ... types of RNA polymerases that can transcribe different types of RNA. RNA polymerase II, shown here, is ...
