Also know: A mutagen is a substance, such as a chemical, that causes mutations.
An operon is a section DNA containing genes for proteins required for a specific metabolic pathway and
it consists of an operator, promoter, regulatory gene, and genes coding for proteins.
Gene regulation is the ability of an organism to control which genes are transcribed in response to the
environment.
Given a DNA sequence, know how to write the complementary sequence of DNA and know how to
write the mRNA that can be transcribed from the original DNA sequence.
Know how to write the properly balanced equation for the production of glucose during photosynthesis:
6H20 + 6CO2  C6H12O6 + 6O2
Know how to write the properly balanced equation for the respiration of glucose as a cell uses it for food
to release energy:
C6H12O6 + 6O2  6H20 + 6CO2
