immunization

Biotechnology; Genetic engineering

The production of immunity in an individual by artificial means. Active immunization involves the introduction, either orally or by infection, of specially treated bacteria, viruses or their toxins ...

oncogenesis

Biotechnology; Genetic engineering

The progression of cytological, genetic and cellular changes that culminate in a tumour.

selection coefficient (s)

Biotechnology; Genetic engineering

The proportion by which the fitness of a genotype is less than the fitness of a standard genotype, which is usually the genotype with the highest fitness. In general, relative fitness = 1 - s .

recombination fraction

Biotechnology; Genetic engineering

The proportion of gametes that have arisen from recombination between two loci. It is estimated as the number of recombinant individuals among a set of offspring of a particular mating, divided by ...

recombination frequency

Biotechnology; Genetic engineering

capsid

Biotechnology; Genetic engineering

The protein coat of a virus. The capsid often determines the shape of the virus.

porcine endogenous retrovirus (PERV)

Biotechnology; Genetic engineering

The provirus (q.v.) of a porcine retrovirus. With the increasing interest in the use of pig organs for xenotransplantation to humans, there has been concern that PERVs could be activated after ...
