enzyme that adds Uracil to DNA in bacteria
primase. makes the RNA primer for DNA poly
lung cancer where surgery is never indicated

name of two stress (trauma, burn) induced ulcers
Curling- duodenal ulcer
cushing- assoicated with increased ICP found in stomach, esoph, duo.

if you had excess hair? inner cortex- sex hormones

if you have weight gain? mid cortex- cortisol
why do you only get a small increase in MAP with running? what decreases to allow this?

what to integrins do?
in hemidesmosomes- mediated cell binding to the BM
