Antibody A blood protein produced to counter an antigen.
Antigen A foreign substance instigating an immune response within the body.
DNA A self-replicating carrier of genetic material; the main constituent of chromosomes.
Host Cell A living wherein a virus multiplies.
Lymphocyte A white blood cell with a single round nucleus.
Lysogenic Cycle One of two cycles of viral reproduction, characterized by the insertion of the virus' genetic material into the host's genome
Lytic Cycle One of two cycles of viral reproduction, characterized by the eventual destruction of the infected cell.
Membranous Envelope The double-layered membrane encasing a eukaryotic cell.
Mucous Membrane An epithelial membrane that secretes mucous.
Nucleic Acid Core A core of acids containing genetic instructions for viral activity and reproduction.
Phagocytic White Blood Cell White blood cells that neutralize harmful foreign substances through ingestion.
Primary Line of Defence Includes natural non-specific defences such as skin, chemicals, and mucous membranes.
Protein Capsid The protein shell of a virus.
RNA A nucleic messenger acid who function is to carry instructions from DNA for protein synthesis.
Secondary Line of Defence The internal defences of the body including antibody generation.

Ecological Role The placement of an organism in a hierarchy of interactions between it and other organisms.
Fermentation The chemical breakdown of a substance through microorganisms.
Motility The characteristic of being able to move actively and/or spontaneously.
Mutation An alteration in a genome's structure, usually resulting in an unprecedented variant form.
Photosynthesis The process through which some plants utilize sunlight to synthesize food products from water and carbon dioxide.
Prokaryote A microscopic unicellular organism with no clear nucleus.
