    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
