central dogma: information is coded in DNA -> RNA -> protein DNA is self-replicating some things on this planet can take RNA and make DNA, so central dogma doesn’t always hold some organisms can replicate RNA nucleic acids in general can be self-replicating can’t go backwards from a protein to RNA efflux pump is controlled: o by a gene at the level of transcription (mRNA) o by the abundance of mRNA (post-transcriptional) o at level of translation o post-translational transcriptional/post translational promoter controls the expression of the gene gene expression can be constitutive (always on), induced, repressed coding region is what makes mRNA mRNA breaks down (classic case of post-transcriptional control) faster to detect changes in transcript than in protein COXIII is a housekeeping gene – required to keep things living and is constitutive amino acid has amino, carboxy, and R groups 20 essential amino acids (do not need to know them)
