I am doing genome project in bacteria so i want details?

i want to write some assignment so pls help me

I am doing genome project in bacteria so i want details?
You better get out of that Bacteria. It could kill you

Bacteria consist of only a single cell, but don't let their small size and seeming simplicity fool you. They're an amazingly complex and fascinating group of creatures. Bacteria have been found that can live in temperatures above the boiling point and in cold that would freeze your blood. They "eat" everything from sugar and starch to sunlight, sulfur and iron. There's even a species of bacteria—Deinococcus radiodurans—that can withstand blasts of radiation 1,000 times greater than would kill a human being.





Classification





Leucothrix mucor


Appl. Environ. Microbiol. 55:1435-1446, 1989





Bacteria fall into a category of life called the Prokaryotes (pro-carry-oats). Prokaryotes' genetic material, or DNA, is not enclosed in a cellular compartment called the nucleus.





Bacteria and archaea are the only prokaryotes. All other life forms are Eukaryotes (you-carry-oats), creatures whose cells have nuclei.








Early Origins





Bacteria are among the earliest forms of life that appeared on Earth billions of years ago. Scientists think that they helped shape and change the young planet's environment, eventually creating atmospheric oxygen that enabled other, more complex life forms to develop. Many believe that more complex cells developed as once free-living bacteria took up residence in other cells, eventually becoming the organelles in modern complex cells. The mitochondria (mite-oh-con-dree-uh) that make energy for your body cells is one example of such an organelle.





What They Look Like





Ball-shaped Streptococci


Simonson, ASM MicrobeLibrary





There are thousands of species of bacteria, but all of them are basically one of three different shapes. Some are rod- or stick-shaped and called bacilli (buh-sill-eye).





Others are shaped like little balls and called cocci (cox-eye).





Some bacterial cells exist as individuals while others cluster together to form pairs, chains, squares or other groupings.





Where They're Found

Bacteria live on or in just about every material and environment on Earth from soil to water to air, and from your house to arctic ice to volcanic vents. Each square centimeter of your skin averages about 100,000 bacteria. A single teaspoon of topsoil contains more than a billion (1,000,000,000) bacteria.





How They Move





Bacterium with flagella


Harwood, ASM MicrobeLibrary





Some bacteria move about their environment by means of long, whip-like structures called flagella. They rotate their flagella like tiny outboard motors to propel themselves through liquid environments. They may also reverse the direction in which their flagella rotate so that they tumble about in one place.





Other bacteria secrete a slime layer and ooze over surfaces like slugs. Others are fairly stationary.





What They Eat





Some bacteria are photosynthetic (foe-toe-sin-theh-tick)—they can make their own food from sunlight, just like plants. Also like plants, they give off oxygen. Other bacteria absorb food from the material they live on or in. Some of these bacteria can live off unusual "foods" such as iron or sulfur. The microbes that live in your gut absorb nutrients from the digested food you've eaten.





Many more interesting facts about bacteria can be found throughout the Microbe website, so keep clicking and reading.
Reply:I think you are not a really scientific. for a "Genome Project" you need ay least to choose an species fron the thousands that they are. I think you have not an adjusted idea that you want
