If something goes wrong during transcription…

• The order of the codons will be wrong

• It’s cool, everything will probably work out

• Translation will fix it

• Cytoplasm

All of your cells have the same exact DNA. How can different cells do different things?

• Genes fit better on some cells

• Regulators… mount up

• Gene expression is the same in all cells

• Gene regulation allows the cell to choose what genes are expressed

Describe this model of DNA

• It is perfect

• It is wrong because the base pairs are wrong

• It is wrong because the proteins are wrong

• It is right because the base pairs are correct
