What is a gene?
DNA codes for a protein
What are ribosomes?
Rees: DNA that codes for a 16S RNA sequence. Google: a minute particle consisting of RNA and associated proteins, found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins.
What is special about archae?
Do not cause disease in humans or animals
What are the two basic needs of life?
Source of carbon Source of electrons
What are three types of archae?
Thermophiles Halophiles Methanogens

Which bacterial genus is responsible for the most illnesses and greatest variety of disease?
What is special about mycoplasmatles?
Lack cell wall Smallest self-replicating organism
What does pleomorphic mean?
Looks different each time viewed
Which phylum is high G+C?
Name the four ways bacteria reproduces
Binary fission - primary reproduction Budding - yeasts Snapping - chisms (sp) fragmentation Spores - not endospores
Name the characteristics of archae
Lack peptidoglycan Cocci, bacilli, spirals Non-disease causing in humans
Name two Gram positive bacteria, low and high G+C
Firmicutes - C. diff low G+C Actinobacteria - high G+C
