Rna polymerases

RNA polymerase

(Science: enzyme molecular biology) An enzyme that polymerise ribonucleotides in accordance with the information present in dNA.

prokaryotes have a single enzyme for the three rNA types that is subject to stringent regulatory mechanisms. Eukaryotes have type I that synthesises all rRNA except the 5S component, type II that synthesises mRNA and hnRNA and type III that synthesises tRNA and the 5S component of rRNA.

Re: Totipotent Stem Cell From Molecular Components

... protein is the average of the gene expression in # of strands of mRNA * 100. I am getting the protein this way. I take the results of PCR and put it in a test tube with RNA polymerases, Ribosomes, and other proteins that help with protein synthesis. I then ...

Re: Isolation during transcription

... higher the yield of polymerase If all you want to do is isolate some RNA polymerase, there are far easier ways to do it (and which don't involve viruses). In fact, some of these polymerases are sold commercially. then you need a technique to synthesis telomerase ...

the RNA synthesized on one of the DNA strands is ..........?

Yes, it is all of them. All RNAs are synthesized by RNA polymerases, and all RNA polymerases use one strand of DNA as the template strand to synthesize single-stranded ...
