- Transcription
- 1.)Sequence of genes have to be copied and transported to protein synthesis
- Shorter molecules of RNA produced
- 2.) Gene unwinds
- DNA helicase, a new codon starts
- Hydrogen bonds between bases break
- DNA helicase, a new codon starts
- Two strands
- Sense
- '3-5' '5-3'
- code for protein to be synthesised
- Antisense
- Complementary copy of sense.
- Sense
- 3.) RNA nucleotides pair with complementary base pairs.
- Exposed on antisense
- Phosphodiester bonds form between RNA nucleotides
- RNA polymerase
- Stops at end of the gene
- mRNA
- 4.) mRNA detaches from DNA and leaves nucleus through pores
- Helix reforms
- Travels to Ribosome
- Helix reforms
- 1.)Sequence of genes have to be copied and transported to protein synthesis
