Prokryotes
...es are studied by microbiologists along with fungi and algae. This field of study is important research these days because it greatly contributes to the studies of medicine, genetics and engineering. “Prokaryotes are single celled organisms that do not have a nucleus, mitochondria or any other membrane bound organelles.” (“The Prokaryotes”). Prokaryotes are generally bigger then .01 micrometer and no greater then 10 micrometer. There is no membrane structure independent of the plasma membrane, and the ribosomes are slightly smaller then eukaryote cells. Most prokaryotes have cell walls composed of peptidoglycan, a single large polymer of amino acids and sugar. Also in prokaryotes it never forms tisuues and the DNA is attached to the cell membrane. The structure of Prokaryotes is very simple and basic. “The cell wall is often a complex mixture of lipids, carbohydrates, and muccopeptides.” (“Prokaryotes”) The cell wall covers the outer surface of the cell membrane. All prokaryotes are unicellular, and most of the cells are all the same. Prokaryotes are different from eukaryotes because they are multicellular and they are 10 times the size of prokaryotes. Although prokaryotes don’t reproduce “they are not without the ability to exchange genes and undergo genetic recombination.” (“Biological Identity of Prokaryotes”) Bacteria can exchange genes through conjugation, transduction and transformation. Conjugation uses cell to cell contact also known as DNA. While transduction transfers a virus of genes between other bacteria, and transformation is when DNA is released to a new environment. “Genetic recombination can follow the transfer of DNA from one cell to another leading to the emergence of a new genotype It is common for DNA to be transfe...
