<span>Cocaine Preparations
-Coca leaves --> Coca Paste (60% pure): Not water soluble, so you can't inject it into the bloodstream -- you need an additional chemical step to turn the paste into crystal powder that can be injected or snorted
-Coca --> Cocaine Hydrochloride (99% pure): Doesn't hold up very well to heat, so you can't smoke cocaine hydrochloride
-Cocaine Hydrochloride (99% pure) --> Free-Base Cocaine or Crack Cocaine:
-Reconvert cocaine hydrochloride back to base state by removing hydrochloride from cocaine (that's why it's called free-base cocaine)
-Crack cocaine is a crystallized form, mixture of cocaine and baking soda
-75% pure
-Can be used at lower doses and is much cheaper than cocaine
-Can be smoked</span>

I need to go, but I hope my bullfrog example will help you answer your questions for Siberian wood frog. :)
DNA polymerase III has a subunit for proofreading during DNA replication. As replication continues and
the polymerase III enzyme detects a mismatched base pair, through a deformity in the double helix structure, the
polymerase backs up, nicks the mismatched base and replaces it with the correct
base before continuing replication.
