DNA A macromolecule known as a nuclei acid , shaped as a double helix with long sugar and phosphate groups along with nitrogenous bases ATGC
Host cell An animal or plant on or in which a parasite or commensalism organism lives
Lymposyte The white blood cell of the blood derived from the stem cells of the lymphoid series of vertebrates.
Lysogenic cycle A viral reproduction involved by integration of the bacteriophage nucleic acid into the host bacterium so genome or formations of a circular replicant in the bacterium so cytoplasm
Lytic cycle The main method of viral reproduction because it ends in the lysis of the infected cell releasing the progeny viruses that will in turn spread and infect other cells
Membranous envelope A double layer of lipid, contains proteins that surrounds biological cells
Mucous membrane An epithelial tissue that secretes mucous and that lines many body cavity a and tubular organs

Protein Capsid The capsid is the protein shell of any virus. Made up of many oligomrric structural subunits called protomers
RNA Ribonucleic acid that is present is all living cells. It is the messenger of the cell carri g instructions from Dna for controlling the synthesis and proteins
Secondary line of defense A group of cells, tissues and organs that work together to protect the body (immune system)
Tertiary line of defense Anything such as antibodies, antigens or any invaders that pass through the first and second line of defence
Viral speciacity A virus is selective in the organisms it infects, the type of cells and the disease it produces
White blood cell Fighting blood cell ( leukocyte )
Aerobic respiration "With air" breathing where oxygen is needed
Antibiotic A medicine that inhibits the growth of or destroys micro organisms
Antiseptic Substances that prevent the growth of disease-causing micro organisms
Binary fission Is a kind of asexual reproduction, most common use of reproduction in prokaryotes
Classification The process of classifying something according to shared equalities or characteristics
Conjugation The formation or existence of a link or connection between things in particular.
Disinfectant A chemical liquid that destroys bacteria
Ecological role A niche and position a species has in its environment
Fermentation A metabolic process that converts sugars to acids, gases or alcohol it occurs in yeast and bacteria
Motate To move from one location to the next
Mutate Change or cause to change in form or nature
Mutation The action or process of mutating from something harmul
