- takes place in the nucleus
- DNA double helix unzip/ unwind strands are broken this reaction is catalysed by the enzymes DNA HELICASE
- The exposed DNA Nucleotides complenary base pairs with free activated RNA nucletioides in the nucleus’s
- Enzyme RNA POLYMERASE joins RNA nucleotide together in a condensation reaction.
- m-RNA detaches from the DNA
- m-RNA Protected is completed to the DNA coding strand
- m-RNA leaves the nucleus though the pore in the nucleus envelope and attaches to the ribosome in the cytoplasm.
Steps of Transcription
Transcription takes place in steps: initiation, elongation, and termination.
- Initiation is the beginning it when the enzymes catalyst RNA polymerase which makes the DNA to unwind
- This helps m-RNA
- Elongation is the when you add more nucleotides to the mRNA strand.
- Termination is the ending of transcription, its when the rna polymerase meets a STOP CODON.
