The development of transgenic animals to produce human proteins for medical use..
Industry:Biology
Artificially constructed cloning vector containing the cos gene of phage lambda. Cosmids can be packaged in lambda phage particles for infection into E. coli; this permits cloning of larger DNA fragments (up to 45kb) than can be introduced into bacterial hosts in plasmid vectors..
Industry:Biology
In genetics, a type of mutation due to replacement of one nucleotide in a DNA sequence by another nucleotide or replacement of one amino acid in a protein by another amino acid.
See also: mutation.
Industry:Biology
The breaking during meiosis of one maternal and one paternal chromosome, the exchange of corresponding sections of DNA, and the rejoining of the chromosomes. This process can result in an exchange of alleles between chromosomes.
See also: recombination.
Industry:Biology
The treatment of injury or disease at the molecular level. Examples include the use of DNA-based diagnostic tests or medicine derived from DNA sequence information..
Industry:Biology
The study of the physical appearance of chromosomes.
See also: karyotype.
Industry:Biology
The group or recognisable pattern of symptoms or abnormalities that indicate a particular trait or disease..
Industry:Biology
A disorder caused by mutation of a single gene.
See also: mutation, polygenic disorder.
Industry:Biology
An area of the chromosome that stains differently from areas around it.
