Definition: an infectious agent that replicates only in the cells of living hosts; containing DNA or RNA which is carried in a shell called the viral coat; no cytoplasm or organelles |
|
|
Vaccine |
Definition: a substance used to control the production of antibodies and strengthen the body's immune system against one or several diseases |
|
|
Anti-Viral |
Definition: an agent that kills a virus and destroys its ability to grow and reproduce |
|
|
Bacteria |
Definition: unicellular microorganisms that have a cell wall and organelles but no nuclei and can sometimes cause disease |
|
|
Parasite |
Definition: an organism that lives in or on another organism and benefits without offering any benefit in return |
|
|
Prokaryote |
a microscopic single-celled organism that doesn't contain a nucleus or membrane-bound organelles |

Definition: any organism that can spread infectious disease to another organism through bites, scratches, body fluids, or other contact |
|
|
Fungi |
Definition: a diverse group of eukaryotic unicellular, multi cellular or syncyital spore-producing organisms that live by decomposing and absorbing the organic material in which they grow |
|
|
Protein Coat |
Definition: the coiled or polyhedral structure, composed of proteins, that encloses the nucleic acid of a virus |
|
|
Tail Fiber |
Definition: a thin long rod like structure that is appended to the tail of prokaryotic viruses and used for attachment to the host cell |
|
|
Cilia
|
Definition: short, microscopic, hair like vibrating structures |

Mitosis
|
Definition: a type of cell division that results in two daughter cells having the same number and type of chromosomes as that of the parent nucleus |
|
|
Meiosis
|
Definition: a type of cell division that results in four daughter cells each having half the number of chromosomes as that of the parent cell |
|
|
Biotechnology
|
Definition: the use of organisms or biological processes for industrial and other purposes, especially for the production of antibiotics, hormones, etc. |
|
|
Binary Fission
|
Definition: a type of asexual reproduction in which a parent cell divides into two daughter cells which are both the same size and are exact copies of the parent cell |
|
|
Virion
|
Definition: the infectious version of a virus as it exists outside the host cell, which is made up of a nucleic acid core, a protein coat, and, in certain species, an external envelope |
