6. What is the first stage of transcription
- Hydrogen bonds between DNA break
- RNA polymerase lines up free RNA
- RNA polymerase attaches to DNA
- mRNA is copied
7. What is the use of mRNA
- To carry genetic code from DNA to cytoplasm
- Carries amino acids to ribosome
- To catalyse polypeptide chain
- To move DNA along and form mRNA strand
8. What is the last step of transcription?
- mRNA moves out through a nuclear pore to attach to a ribosome
- RNA reaches stop codon and detaches from DNA
- Hydrogen bonds reform
- tRNA molecules carry amino acids to the ribosome
9. Where does translation occur?
- Ribosomes in cytoplasm
- Mitochondria
- Nucleolus
- Vacuole
