Study Notes

Steps of Transcription

Initiation: RNA polymerase binds to the DNA and unwinds the double helix to begin transcription.
Elongation: RNA nucleotides are synthesized using the DNA template strand, elongating the newly formed mRNA strand.
Termination: Once elongation is complete, the newly synthesized mRNA strand exits the nucleus, ready for translation.
