Transcription

• 1. RNA polymerase attaches to the start codon of a gene
• 2. section of DNA unwinds by hydrogen bonds breaking between the bases of the middle of the double helix
• 3. one DNA strand acts as a template strand
• 4. RNA polymerase lines up free RNA nucleotides this forms mRNA
• 5. once RNA polymerase has passed the DNA strand winds back up again
• 6. once RNA reaches end of the codon it detaches from DNA
• 7. mRNA moves through nuclear pore and attaches to ribosome in cytoplasm where translation takes place
