Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.
This man is presenting with signs/symptoms of an inferior wall M.I. (myocardial infarction), a heart attack. He needs to be started on IV fluids with morphine, oxygen, nitroglycerin, and aspirin. However, it is imperative that before administering nitro/nitrates, he denies having taken any sexual meds for erectile dysfunction (e.g. Viagra) within the past 24 hours.

When the lac operon controls the expression of proteins in the E.coli cell that can break down lactose into two sugars, glucose and galactose. When lactose is present, it binds to the repressor that typically sits on the lac operon, changing the repressor's conformation such that it can no longer bind to the lac operon. Because of this, RNA polymerase can now transcribe the gene into mRNA, <span>which in turn is translated into the proteins that can break down lactose.</span>
