Description : This image shows a line drawing of a bacterium with its chromosomal DNA and several plasmids within it. The bacterium is drawn as a large oval. Within the bacterium, small to medium size circles illustrate the plasmids, and one long thin closed line that intersects itself repeatedly illustrates the chromosomal DNA.
English: A reworked version of File:Biological_cell.svg. Diagram of a typical animal cell. Organelles are labelled as follows: Nucleolus; Nucleus; Ribosomes (dots on rough reticulum walls) Vesicle; Rough endoplasmic reticulum; Golgi apparatus (or "Golgi body") Cytoskeleton; Smooth endoplasmic reticulum; Mitochondrion; Vacuole; Cytosol; Lysosome ...
Description : This image shows a line drawing that compares the activity of non-integrating plasmids, on the top, with episomes, on the bottom, during cell division. The upper half of the image shows a bacterium with its chromosomal DNA and plasmids dividing into two identical bacteria, each with their chromosomal DNA and plasmids.

Organelles are parts of the cell that are adapted and/or specialized for carrying out one or more vital functions, analogous to the organs of the human body (such as the heart, lung, and kidney, with each organ performing a different function). [2]
The cells after transformation are exposed to the selective media, and only cells containing the plasmid may survive. In this way, the antibiotics act as a filter to select only the bacteria containing the plasmid DNA. The vector may also contain other marker genes or reporter genes to facilitate selection of plasmids with cloned inserts.
The plasma membrane or bacterial cytoplasmic membrane is composed of a phospholipid bilayer and thus has all of the general functions of a cell membrane such as acting as a permeability barrier for most molecules and serving as the location for the transport of molecules into the cell.
Explanation of the levels in the human body; defines the column labels in the next table. Level Definition Organ systems: A biological system consisting of a group of organs that work together to perform one or more functions. Organ sub-systems A biological system consisting of a group of organs that work together to perform just one function.
