DNA Transcription

DNA Transcription is the process genetic information being transcribed from DNA to RNA. The transcribed DNA message is used to make proteins. DNA is inside the nucleus of a cell. The coding of DNA is made up of guanine, denine, cytosine, and thymine. But when DNA is transcribed to RNA, thymine becomes Uracil. The steps are

  1. DNA unzips, hydrogen bonds are broken, Helicase enzyme unwinds and separates DNA strands
  2. RNA polymerase(an enzyme) adds RNA nucleotides to one strand of the opened DNA
  3. The new mRNA strand breaks free and leaves the nucleus
  4. Hydrogen bonds reform between the 2 stands of DNA
  5. mRNA is now carrying DNA’s message for how to make one protein
