https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3465734/RNA transcribed by RNAP II is processed to mature RNA through the steps of 5′ capping, intron removal, and 3′ end formation. These processes are frequently coupled with transcription, and all involve the CTD
Thanks a lot.Ygggdrasil said:
RNA Polymerase is an enzyme responsible for transcribing DNA into RNA in eukaryotic cells. It is a key player in gene expression and plays a vital role in the synthesis of proteins.
There are three types of RNA Polymerase in eukaryotes: RNA Polymerase I, RNA Polymerase II, and RNA Polymerase III. Each type is responsible for transcribing different types of RNA molecules.
RNA Polymerase II is responsible for transcribing messenger RNA (mRNA), which carries genetic information from the DNA to the ribosomes for protein synthesis.
RNA Polymerase II binds to specific DNA sequences called promoters, which are located at the beginning of a gene. These promoters signal the start of transcription and help the enzyme to accurately initiate the process.
Transcription factors are proteins that bind to specific DNA sequences and help to regulate the activity of RNA Polymerase. They can either enhance or inhibit the binding of RNA Polymerase to the DNA, thus controlling the rate of transcription.
