After reading the material and viewing the links provided please participate in the discussion. It is so hard to know what to tell you or not tell you about drugs. I hesitated on even including this chapter in the online material. I would so much rather we be in a classroom setting. The book is out dated so I inluded a few links for you to view. Comment on the topics below to earn your grade this week. 1. Obviously people don't wake up one day and decide to become an addict, but because these drugs are so powerful and habit forming that is indeed what happens to most users. Why do you think that people turn to drugs and use for the first time? 2. Explain how a persons physical appearance can change so drastically using methamphetamines and why they wuld do that to themselves. 3. What is something about drugs I could tell you that would pursuade you from ever using them? 4. Name a goal you would like to achieve after HS and give me an example of how drugs could make that impossible.

Poliovirus is an rna virus of the picornavirus group, which uses its rna as mrna. at its 5' end, the rna genome has a viral protein (vpg) instead of a cap. this is followed by anontranslated leader sequence, and then a single long protein-coding region (~7000 nucleotides), followed by a poly-a tail. observations were made that used radioactive amino acid analogues. short period use of the radioactive amino acids result in labeling of only very long proteins, while longer periods of labeling result in several different short polypeptides. what conclusion is most consistent with the results of the radioactive labeling experiment? a) host cell ribosomes only translate the viral code into short polypeptides. b) the rna is only translated into a single long polypeptide, which is then cleaved into shorter ones. c) the rna is translated into short polypeptides, which are subsequently assembled into large ones. d) the large radioactive polypeptides are coded by the host, whereas the short ones are coded for by the virus.
