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.
