What is the important role of RNA polymerase in the process?
RNA polymerase is a multi-unit enzyme that synthesizes RNA molecules from a template of DNA through a process called transcription. The transcription of genetic information into RNA is the first step in gene expression that precedes translation, the process of decoding RNA into proteins.
Is there any role for an RNA polymerase in DNA replication quizlet?
Is there any role for an R N A polymerase in D N A replication? a.No, only D N A polymerases function in D N A replication.
What are two functions of RNA polymerase?
RNA polymerases transcribe the information in DNA into RNA molecules that have a variety of functions, including messenger RNA, transfer RNA, ribosomal RNA (for protein synthesis), ribozymes (for catalysis), and microRNA (for regulation of gene expression).
What is the role of DNA polymerase?
The primary role of DNA polymerases is to accurately and efficiently replicate the genome in order to ensure the maintenance of the genetic information and its faithful transmission through generations. In addition to their role in replication, DNA polymerases play a central role in most of these pathways.
What is the role of RNA primers in DNA replication quizlet?
A primer is a short strand of RNA or DNA (generally about 18-22 bases) that serves as a starting point for DNA synthesis. It is required for DNA replication because the enzymes that catalyze this process, DNA polymerases, can only add new nucleotides to an existing strand of DNA.
What is the function of these short RNA segments during replication?
Initiation of Okazaki fragments with RNA primers. Short fragments of RNA serve as primers that can be extended by DNA polymerase. To form a continuous lagging strand of DNA, the RNA primers must eventually be removed from the Okazaki fragments and replaced with DNA. In E.
