| killer plasmid | <molecular biology> These plasmids are found in some strains of Kluyveromyces marxianus where the cells contain multiple cytoplasmic copies of dsDNA plasmids. Such cells secrete a glycoprotein toxin. The plasmids and the killer function can be transferred to yeast. (18 Nov 1997) |

| F plasmid | The prototype conjugative plasmid associated with conjugation in the K-12 strain of Escherichia coli. Synonym: F agent, F-factor, F genote, F-genote, fertility agent, fertility factor, sex factor. (05 Mar 2000) |
| gene cloning | <molecular biology> The insertion of a DNA sequence into a vector that can then be propagated in a host organism, generating a large number of copies of the sequence. (18 Nov 1997) |
| cell cloning | The process of producing a group of cells (clones), all genetically identical, from a single ancestral cell. (12 Dec 1998) |
| megabase cloning | <molecular biology> The cloning of very large DNA fragments. (29 Oct 1998) |
| cloning | <molecular biology> The process whereby clones are established asexually, where cells all genetically identical, to a single ancestor. In recombinant DNA technology, the use of DNA manipulation procedures to produce multiple copies of a single gene or segment of DNA is referred to as cloning DNA. The term covers various manipulations for isolating and establishing clones. In simple systems single cells may be isolated without precise knowledge of their genotype. In other systems partial or complete selection of chosen genotypes can be manipulated with gene cloning. In plants the term refers to natural or artificial vegitative propagation. (12 Mar 1998) |
| cloning, cell | The process of producing a group of cells (clones), all genetically identical, from a single ancestor. (12 Dec 1998) |
| cloning, DNA | The use of DNA manipulation procedures to produce multiple copies of a single gene or segment of DNA. (12 Dec 1998) |
| cloning, molecular | The insertion of recombinant DNA molecules from prokaryotic and/or eukaryotic sources into a replicating vehicle, such as a plasmid or virus vector, and the introduction of the resultant hybrid molecules into recipient cells without altering the viability of those cells. (12 Dec 1998) |
| cloning, organism | The formation of one or more genetically identical organisms derived by vegetative reproduction from a single cell. The source nuclear material can be embryo-derived, foetus-derived, or taken from an adult somatic cell. (12 Dec 1998) |
| 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) |
| 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) |
