1 Transcription
- Polymerase
- The thing that copies it over
- Promoter
- The structure that chooses which genes to copy
- Coding Region
- The area of DNA to be copied
- mRNA
- What the polymerase outputs (DNA copy inverse)
- Terminator
- The tail end of the coding region that folds making the RNA fall off
- This creates the mRNA and the siRNA and tRNA
2 Outside signals
- Signals to outside receptors create positive or negative transcription
factors
- These can be activated by internal signals
- positive transcription factors allow for and encourage transcription
- negative transcription factors cause the release of a molecule that take the slot of polymerase shutting down the gene and not allowing for transcription
3 Mutations
- There are different types of mutations such as a substitution mutation
