Antigenic drift is a mechanism for variation in viruses that involves the accumulation of mutations within the genes that code for antibody-binding sites.
Antigenic shift is the process by which two or more different strains of a virus, or strains of two or more different viruses, combine to form a new subtype having a mixture of the surface antigens of the two or more original strains.
Bacteria (common noun bacteria, singular bacterium) is a type of biological cell.
Biology is the natural science that studies life and living organisms, including their physical structure, chemical composition, function, development and evolution.
Chinese hamster ovary (CHO) cells are an epithelial cell line derived from the ovary of the Chinese hamster, often used in biological and medical research and commercially in the production of therapeutic proteins.
The term cultivarCultivar has two denominations as explained in Formal definition.
A fungus (plural: fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms.
Genetic engineering, also called genetic modification or genetic manipulation, is the direct manipulation of an organism's genes using biotechnology.
A genetic isolate is population of organisms that has little genetic mixing with other organisms within the same species.
Genetics is the study of genes, genetic variation, and heredity in living organisms.
Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically.
Influenza, commonly known as "the flu", is an infectious disease caused by an influenza virus.
A lineal descendant, in legal usage, is a blood relative in the direct line of descent – the children, grandchildren, great-grandchildren, etc.
A microbiota is an "ecological community of commensal, symbiotic and pathogenic microorganisms" found in and on all multicellular organisms studied to date from plants to animals.
A mouse (Mus), plural mice, is a small rodent characteristically having a pointed snout, small rounded ears, a body-length scaly tail and a high breeding rate.
In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements.
A nucleic acid sequence is a succession of letters that indicate the order of nucleotides forming alleles within a DNA (using GACT) or RNA (GACU) molecule.
In biological taxonomy, race is an informal rank in the taxonomic hierarchy, below the level of subspecies.
Rats are various medium-sized, long-tailed rodents in the superfamily Muroidea.
Rice is the seed of the grass species Oryza sativa (Asian rice) or Oryza glaberrima (African rice).
In biology, a species is the basic unit of classification and a taxonomic rank, as well as a unit of biodiversity, but it has proven difficult to find a satisfactory definition.
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in a taxonomic hierarchy.
A virus is a small infectious agent that replicates only inside the living cells of other organisms.
