  • Transcription is the formation of an RNA strand from a DNA template within the nucleus of a cell. (bartleby.com)
  • Before we get into this, let's first review how RNA can transmit genetic information contained in DNA to the rest of the cell. (nagwa.com)
  • Our genes are made up of hundreds to millions of building blocks, called DNA nucleotides, and if just a single nucleotide of DNA becomes mutated it might cause a devastating genetic disease. (sciencebuddies.org)
  • The diagrammatic representation of distances between the adjacent genes which is directly proportional to the frequency of recombination between them is called genetic mapping. (brainkart.com)
  • The flow of genetic information in cells is that DNA is first transcribed into RNA through a process called transcription. (proprofs.com)
  • In this paper, we report four sets of crystal structures of bacterial initially transcribing complexes that demonstrate and define details of stepwise, RNA-extension-driven displacement of the "σ-finger" of the bacterial transcription initiation factor σ. (osti.gov)
