QuestionAnswer
antibody a blood protein produced in response to and counteracting a specific antigen.
antigen a toxin or other foreign substance that induces an immune response in the body
DNA deoxyribonucleic acid, a self-replicating material present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.
host cell a living cell in which a virus multiplies.
lymphocyte a form of small leukocyte (white blood cell) with a single round nucleus, occurring especially in the lymphatic system.
lysogenic cycle Lysogeny, or the lysogenic cycle, is one of two cycles of viral reproduction
lytic cycle s one of the two cycles of viral reproduction (referring to bacterial viruses or bacteriophages),
membranous envelope The double-layered membrane enclosing the nucleus of a eukaryotic cell.
mucous membrane an epithelial tissue that secretes mucus and that lines many body cavities and tubular organs including the gut and respiratory passages.
nucleic acid core an outer protein coating or capsid, and sometimes an outer envelope made of protein and phospholipid membranes derived from the host cell.
phagocytic white blood cell that break down bacteria and other microorganisms, foreign particles, and cellular debris.
primary line of defence The first line of defence (or outside defence system) includes physical and chemical barriers that are always ready and prepared to defend the body from infection.
protein capsid A capsid is the protein shell of a virus
RNA ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins,
secondary line of defence The second line of defense is nonspecific resistance that destroys invaders in a generalized way without targeting specific individuals
tertiary line of defence A Tertiary Line of Defense is anything like antibodies, antigens, or any invaders that pass through the first and second line of defense
viral specificity Viral specificity. Definition. Refers to the specific type of cells that a virus can infect
white blood cell have a nucleus and cytoplasm and help protect the body from infection and disease through specialized neutrophils
aerobic respiration s the process of producing cellular energy involving oxygen.
antibiotic a medicine (such as penicillin or its derivatives) that inhibits the growth of or destroys microorganisms.
antiseptic relating to or denoting substances that prevent the growth of disease-causing microorganisms.
bacteria a member of a large group of unicellular microorganisms that have cell walls but lack organelles and an organized nucleus, including some that can cause disease.
binary fission is a kind of asexual reproduction. It is the most common form of reproduction in prokaryotes such as bacteria
classification the arrangement of animals and plants in taxonomic groups according to their observed similarities
conjugation the temporary union of two bacteria or unicellular organisms for the exchange of genetic material.
disinfectant a chemical liquid that destroys bacteria.
ecological role An ecological niche is the role and position a species has in its environment; how it meets its needs for food and shelter
fermentation the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat.
motility In biology, motility is the ability of organisms and fluid to move or get around. A microbiologist might test and compare the motility of various single-celled organisms.
mutate/mutation A mutation is a genetic change that causes new and different characteristics, like the mutation on the dog's DNA that makes its tail shorter than its ancestors' tails.
photosynthesis the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.
prokaryote a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles.
resistant/resistance giving, capable of, or exhibiting resistance —often used in combination. a drug-resistant strain of virus.
