TRANSCRIPTION


  • Transcription is the process of copying genetic information from one strand of DNA into RNA.
  • This process is governed by the principle of complementarity, similar to DNA replication.
  • However:
  • In transcription, adenosine (A) in DNA pairs with uracil (U) in RNA instead of thymine (T).

  • In replication:
  • The entire DNA molecule is copied.
  • Both DNA strands are involved.
  • The result is a complete duplication of the organism’s DNA.
  • In transcription:
  • Only a specific segment of DNA is transcribed.
  • Only one of the two strands is copied into RNA.
  • It is essential to define boundaries:
  • These boundaries mark the starting and ending points of the region to be transcribed.
  • They also specify which DNA strand will act as the template.
