Document Summary
Plasmids may carry genes for such activities as antibiotic resistance, tolerance to toxic metals, the production of toxins, and the synthesis of enzymes. Plasmids can be transferred from one bacterium to another. Ribosomes which function as the sites of protein synthesis. Cells that have high rates of protein synthesis, such as those that are actively growing, have a large number of ribosomes. Ribosomes are composed of two subunits, each of which consists of protein and a type of rna called ribosomal rna (rrna) Several antibiotics work by inhibiting protein synthesis on prokaryotic ribosomes. Material held inside a cell, often consisting of reserve deposits. Within the cytoplasm of prokaryotic cells are several kinds of reserve deposits, known as inclusions. Cells may accumulate certain nutrients when they are plentiful and use them when the environment is deficient. Volutin represents a reserve of inorganic phosphate (polyphosphate) that can be used in the synthesis of atp.
