Document Summary
Cell and molecular biologists have focused considerable research activities on a small number of (cid:498)representative(cid:499) or model. Nevertheless, six model organisms one prokaryote and five eukaryotes have captured much of the attention: a bacterium e. coli; a budding yeast, saccharomyces cerevisiae; a flowering plant, Arabidopsis thaliana; a nematode, caenorhabditis elegans; a fruit fly, drosophila melanogaster; and a mouse, mus musculus. Each of these organisms has specific advantages that make it particularly useful as a research subject for answering certain types of questions. Escherichia coli is a rod shaped bacterium that lives in the. Much of basic molecular biology of the cell, including the mechanisms of replication, transcription, and translation, was originally worked out on this one prokaryotic organism digestive tract of humans and other mammals. Saccharomyces cerevisiae, is the least complex of the eukaryotes commonly studied, yet it contains a surprising number of proteins that are homologous to proteins in human cells.
