Know Before You Come

We will have a limited amount of time in our workshop and plan to make the best use of it we can. There is a wide range of topics which you as teachers use in your classrooms and are routinely familiar with. To allow everyone a chance to review topics you haven't looked at in a while, we suggest you look over the following before coming, as we will spend minimal time on review of this information. Some of the web sites listed below may also be of interest for use in your classrooms.

1. structure of prokaryotic and eukaryotic cells, and cells and viruses
Concentrate on the distinctive characteristics of prokaryotic cells: the lack of membrane-bounded organelles, single circular chromosome (always DNA), 70S ribosomes.

Concentrate on the distinctive characteristics of viruses: either DNA or RNA genome, lack of organelles. Think about this question: are viruses living or nonliving?

A web site containing diagrams and a discussion is:
http://micro.magnet.fsu.edu/cells/index.html
Click on Animal Cells, Bacteria, Plant Cells and Viruses as interested.

2. structure of macromolecules found in cells, important bonds
proteins and amino acids
DNA, RNA and nucleotides
carbohydrates
lipids

A web site with nice diagrams of DNA, RNA, nucleotides, proteins and amino acids is:
http://science.nhmccd.edu/biol/animatio.htm
Click on: Many – Reproduction and Genetics
then on pages as interested. This site has illustrations of DNA replication, transcription and translation as well as the diagrams of the molecules.

covalent bonds
hydrogen bonds
hydrophobic bonds

3. the general process of glucose metabolism
Know that glucose functions as an electron donor, NADH and FADH2 as electron carriers, in respiration ATP is produced when electrons are donated to the electron transport chain, and in aerobic respiration oxygen serves as the final electron acceptor.

4. the distinctive characteristics of prokaryotic genetics
A copy of part of the bacterial chromosome or other genetic elements of one cell can move from one cell to another cell.

Definitions

asepsis	the absence of living microorganisms
sterilization	killing or removal of all living organisms and their viruses
antibody	a protein present in serum or other body fluid that combines specifically with antigen
immunity	the ability of an organism to resist infection
vaccination	inoculation of a host with inactive, killed or weakened pathogens or pathogen products to stimulate protective immunity
