What is an RNA primer? Describe its role in DNA replication. What is the role of DNA polymerase alpha? What are the nitrogenous bases of DNA and RNA? What type of enzyme is DNA polymerase? What is the nucleotide that RNA uses instead of thymidine ("T")?
Transcriptional role in DNA replication: Degradation of RNA primer during DNA synthesisDNA synthesis catalyzed in vitro by E. coli DNA polymeraseI in the presence of single stranded fd DNA or poly (dT) as template is stimulated by RNA primers. When poly(dT) fully or partially saturated with ...
The transcriptional machinery is thought to dissociate from DNA during replication. Certain proteins, termed epigenetic marks, must be transferred from parent to daughter DNA strands in order to maintain the memory of transcriptional states1,2. These pro
RNA Directed DNA Polymerase In subject area: Pharmacology, Toxicology and Pharmaceutical Science Reverse transcriptase (RT), also known as RNA-dependent DNA polymerase, is a DNA polymerase enzyme that transcribes single-stranded RNA into DNA. From: Encyclopedia of Biological Chemistry (Second ...

RNA Polymerase II Function RNA Polymerase II Structure Lesson Summary Frequently Asked Questions What is the role of RNA polymerase II? RNA Polymerase II is responsible for copying or transcribing DNA into a molecule of mRNA. RNA Pol II initiates transcription by binding to a promoter region, copi...
Furthermore, 9458G in the JFH-1 variable region (VR) was responsible for RNA replication activity because of its RNA structures. In conclusion, N3H, high polymerase activity, enhanced kissing-loop interactions, and optimal viral RNA structure in the 3′UTR were required for J6CF replication in...
RNA polymerase locally opens the double-stranded DNA so that one strand of the exposed nucleotides can be used as a template for the synthesis of RNA, a process called transcription.Ineukaryotic cells, activator proteins (some transcription factor proteins) bind to pieces of DNA called enhancers....
