| positional cloning | Cloning a gene based simply on knowing its position in the genome without any idea of the function of that gene. Because this is the reverse of how things have been traditionally done, it has also been called reverse genetics. (12 Dec 1998) |
|---|---|
| self cloning | <molecular biology> Any system in which inappropriate cell types or organisms are eliminated because they possess some character that allows them to die or to remove themselves from the system. Thus a transfected cell with genetic material including a drug resistance marker will be self cloning in the presence of the drug and nontransfected cells will die. (18 Nov 1997) |
| dilution cloning | Cloning by diluting the cell suspension to the point at which the probability of there being more than one cell in the inoculum volume is small. Inevitably on quite a few occasions there will not be any cells. (18 Nov 1997) |
| directional cloning | DNA insert and vector molecules are digested with two different restriction enzymes to create noncomplementary sticky ends at either endof each restriction fragment. This allows the insert to be ligated tothe vector in a specific orientation and prevents the vector fromrecircularising. (09 Oct 1997) |
| DNA cloning | The use of DNA manipulation procedures to produce multiple copies of a single gene or segment of DNA. (12 Dec 1998) |
| expression cloning | <molecular biology> A vector that results in the expression of inserted DNA sequences when propagated in a suitable host cell, i.e. The protein coded for by the DNA is synthesised by the host's system. (06 Aug 1998) |
| adenoviruses, human | Species of the genus mastadenovirus, causing a wide range of diseases in humans. Infections are mostly asymptomatic, but can be associated with diseases of the respiratory, ocular, and gastrointestinal systems. (12 Dec 1998) |
| adenovirus infections, human | Respiratory and conjunctival infections caused by 33 identified serotypes of human adenoviruses. (12 Dec 1998) |
| antigens, human platelet | Human alloantigens expressed only on platelets, specifically on platelet membrane glycoproteins. These platelet-specific antigens are immunogenic and can result in pathological reactions to transfusion therapy. (12 Dec 1998) |
| bites, human | Bites inflicted by humans. (12 Dec 1998) |
| bonding, human-pet | The emotional attachment of individuals to pets. (12 Dec 1998) |
| packed human blood cells | Whole blood from which plasma has been removed; may be prepared any time during the dating period of the whole blood from which it is derived, but not later than six days after the blood has been drawn if separation of plasma and cell's is achieved by centrifugation. (05 Mar 2000) |
| papilloma virus, human | A family of over 60 viruses responsible forcausing warts. The majority of the viruses produce warts on the hands, fingers, and even the face. most of these viruses are innocuous, causing nothing more than cosmetic concerns. Several types of HPV are confined primarily to the moist skin of the genitals, producing genital warts and elevating the risk for cancer of the cervix. These viruses that cause wartlike growths on the genitals and contrribute to cancer of the cervix are sexually transmitted. (12 Dec 1998) |
| parainfluenza virus 1, human | The type species of paramyxovirus also called haemadsorption virus 2 (ha2), which causes laryngotracheitis in humans, especially children. (12 Dec 1998) |
| parainfluenza virus 2, human | A species of rubulavirus associated particularly with acute laryngotracheitis (croup) in children aged 6 months to 3 years. (12 Dec 1998) |
