Study Notes
Transcription
- The process of copying genetic information from DNA genome into a complementary strand of RNA
- Occurs in both prokaryotes and eukaryotes
- Takes place in the cytoplasm of prokaryotes and nucleus in eukaryotes
- RNA polymerase is involved in the process
- No primer is used by RNA polymerase
- Products of transcription are used in protein synthesis
Reverse Transcription
- The reverse process of normal transcription, where RNA template is copied to form a cDNA molecule
- Occurs specifically in retroviruses
- Takes place in the cytoplasm of the host
- Reverse transcriptase is involved in the process
- Lysyl tRNA acts as the primer for reverse transcriptase
- Products of reverse transcription are integrated into the host genome

Description
Learn about the process of transcription, where genetic information from DNA is copied into RNA, and its reverse process, reverse transcription, where RNA is copied to form cDNA. Understand the differences in prokaryotes and eukaryotes.
