| molecular cloning | <molecular biology> The biological amplification of a specific DNA sequence through mitotic division of a host cell into which it has been transformed or transfected. (09 Oct 1997) |
|---|---|
| complementary DNA cloning | <molecular biology, technique> A lab technique where a double-stranded cDNA molecule (or dscDNA) is inserted into a cloning vector (another DNA molecule which will continue to be capable of replication after insertion of foreign material), so that the gene encoded by the cDNA can be expressed (transcribed and used) or so many copies of the gene can be made. (09 Oct 1997) |
| multiple cloning site | Region of a phage or plasmid vector that has been engineered to contain a series of restriction sites that are usually unique within the entire vector. This makes it particularly easy to insert or excise (subclone) DNA fragments. (18 Nov 1997) |
| 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) |
