Extractions: Prokaryotes Characteristics of prokaryotic cells. As mentioned in the previous page, prokaryotes include the kingdoms of Monera (simple bacteria) and Archaea. Simply stated, prokaryotes are molecules surrounded by a membrane and cell wall. Prokaryotic cells lack characteristic eukaryotic subcellular membrane enclosed "organelles", but may contain membrane systems inside a cell wall. Prokaryotic cells may have photosynthetic pigments, such as is found in cyanobacteria ("blue bacteria"). Some prokaryotic cells have external whip-like flagella for locomotion or hair like pili for adhesion. Prokaryotic cells come in multiple shapes: cocci (round), baccilli (rods), and spirilla or spirochetes (helical cells). Pseudomonas bacteria The cell wall is the target for antibiotics, as well as for carbohydrates that our immune system uses to detect infection. A major threat to humankind is the antibiotic-resistant strains of bacteria have been selected by overuse of antibiotics. Sympathy for the life of bacteria If you were bacteria: You have 0.001 times as much DNA as a eukaryotic cell.

This program presents: the discovery of viruses, their structures, how they are studied, and their various modes of infection and replication from the T-4 bacteriaphage to complex retroviruses such as HIV. (18 minutes) The Biology of Bacteria shows: the surprising range of behavior seen in living bacteria, how bacteria obtain nutrients through "external digestion," and how to use sterile techniques for culturing and studying them. The program shows the vital roles bacteria play in maintaining the biosphere through oxygen production (by cyanobacteria), decomposition and nitrogen fixation. (16 minutes)

Raven/Johnson: Chapter 34 Randy Moore, University of MinnesotaMinneapolis Bacteria simply dominate the Earth. Scientists often refer to the Age of the Dinosaurs or the Age of Mammals or discuss the immense diversity and abundance of insects. But, bacteria are the oldest, most diverse, most abundant organisms on Earth. They always have been and, most likely, always will be. Bacteria are able to live in a wide variety of environments. They have been found in the intestines of vertebrates, around volcanic vents at the bottom of the ocean, and in swamps where there is no oxygen. Though some bacteria are rather fragile and will be killed by soap and water, there are some species that are resistant to extreme temperatures, most antibiotics, and perhaps even the vacuum of space.

Extractions: Profiling of gene expression in bacteria is now being used to uncover unknown genes expressed in particular genetic backgrounds or environmental conditions. Obtaining the best possible information from the expected avalanche of such experiments will require standardization of both experimental approach and statistical analysis. The first such experiments reveal challenges, pitfalls and reasonable solutions. Biology has a long history of describing and classifying objects, mostly in structural terms using the techniques and language of systematics. Even genetics, which identifies gene linkage, has often studied genes as individual entities. In these earlier approaches, a cell was considered but a bag of genes and gene products: it was not usual to find biologists asking questions about the collective behavior of these genes and proteins. Because selection pressure may act on any type of organization, the study of whole-genome sequences now enables us to consider whether genomes are simply collections of genes, or whether there is indeed something more to be discovered in terms of the structure and dynamics of cells and organisms at the global level.

http://genomebiology.com/2002/3/10/research/0058

Extractions: Background When there are no strand-specific biases in mutation and selection rates (that is, in the substitution rates) between the two strands of DNA, the average nucleotide composition is theoretically expected to be A = T and G = C within each strand. Deviations from these equalities are therefore evidence for an asymmetry in selection and/or mutation between the two strands. By focusing on weakly selected regions that could be oriented with respect to replication in 43 out of 51 completely sequenced bacterial chromosomes, we have been able to detect asymmetric directional mutation pressures.

General Online Resources on Microbiology With respect to structure, a prokaryote is a small (ca. 1 micron) unicell which exhibits three features, a plasma membrane , a region called a nucleoid (which contains the hereditary material, a circular molecule of bacterial DNA not associated with histone proteins), and ribosomes which are 15-20 nm in diameter and composed of RNA and protein. In addition, most have a bacterial cell wall consisting mostly of peptidoglycan and an outermost layer called a capsule . Some bacteria possess an additional lipopolysaccharide outermost layer and are said to be gram negative. The presence or absence of this layer is important both in the biology of the bacterium and as a diagnostic tool. Many possess mesosomes (function unknown); photosynthetic autotrophs possess photosynthetic membranes. Both of these structures are continuous with the plasma membrane. Reproduction is by binary fission (not mitosis). Some bacteria have flagella. However, when present
