  • vitro
  • Affinity purification of the tobacco plastid RNA polymerase and in vitro reconstitution of the holoenzyme. (springer.com)
  • Transcripts can be used as hybridization probes, templates for in vitro translation, substrates in RNA processing systems, or for exon and intron mapping of genomic DNA. (bio-medicine.org)
  • Here we develop such a cross-chiral RNA polymerase, using in vitro evolution starting from a population of random-sequence RNAs. (nih.gov)
  • catalyse
  • Replicating D- and L-RNA molecules may have emerged together, based on the ability of structured RNAs of one handedness to catalyse the templated polymerization of activated mononucleotides of the opposite handedness. (nih.gov)
  • RNA polymerases catalyse the DNA-dependent polymerisation of RNA. (ebi.ac.uk)
  • consists
  • In archaebacteria, there is generally a single form of RNA polymerase which also consists of an oligomeric assemblage of 10 to 13 polypeptides. (ebi.ac.uk)
  • strand
  • Each RNAP is transcribing an RNA strand , which can be seen branching off from the DNA. (wikipedia.org)
  • With the help of some other molecules, it makes messenger RNA from a strand of a DNA . (wikipedia.org)
  • substrates
  • It is commonly thought that the earliest RNA polymerase and its substrates would have been of the same handedness, but this is not necessarily the case. (nih.gov)
