List the classification of bacteria domain Gram-positive and -negative bacteria, and domain archaea

Phyla-Class-Notes Gram-positive bacteria Firmicutes-Clostridia-low G+C Gram-negative bacteria Chlamydia-Chlamydiae-grow in eukaryotic cells Archaea Euryarchaeota-Methanobacteria-grow methane

9

What is a gene?

DNA codes for a protein

10

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

12

What are the two basic needs of life?

Source of carbon Source of electrons

13

What are three types of archae?

Thermophiles Halophiles Methanogens

14

Name five photosynthetic bacteria

Cyanobacteria-produce O2-Anabaena Chlorobi-green sulfur, anoxygenic-Chlorobium Cholorflexi-green nonsulfur, anoxygenic-Chlorobium Purple sulfur-Chromatium Purple nonsulfur-Rhodospirillum

Which bacterial genus is responsible for the most illnesses and greatest variety of disease?

Streptococcus

16

What is special about mycoplasmatles?

Lack cell wall Smallest self-replicating organism

What does pleomorphic mean?

Looks different each time viewed

18

Which phylum is high G+C?

Acinobacteria

Name the four ways bacteria reproduces

Binary fission - primary reproduction Budding - yeasts Snapping - chisms (sp) fragmentation Spores - not endospores

20

Name the characteristics of archae
