Molecular cloning takes advantage of the fact that the chemical structure of DNA is fundamentally the same in all living organisms. Therefore, if any segment of DNA from any organism is inserted into a DNA segment containing the molecular sequences required for DNA replication, and the resulting recombinant DNA is introduced into the organism from which the replication sequences were obtained ...
Cloning is the process of producing individual organisms with identical genomes, either by natural or artificial means. In nature, some organisms produce clones through asexual reproduction; this reproduction of an organism by itself without a mate is known as parthenogenesis.
A genomic library is a set of clones that together represents the entire genome of a given organism. The number of clones that constitute a genomic library depends on (1) the size of the genome in question and (2) the insert size tolerated by the particular cloning vector system. For most practical purposes, the tissue source of the genomic DNA ...
A cDNA library is a combination of cloned cDNA (complementary DNA) fragments inserted into a collection of host cells, which constitute some portion of the transcriptome of the organism and are stored as a "library". cDNA is produced from fully transcribed mRNA found in the nucleus and therefore contains only the expressed genes of an organism.
The template DNA must be eliminated by enzymatic digestion with a restriction enzyme such as DpnI, which is specific for methylated DNA. All DNA produced from most Escherichia coli strains would be methylated; the template plasmid that is biosynthesized in E. coli will, therefore, be digested, while the mutated plasmid, which is generated in ...
Recombinant DNA (rDNA), or molecular cloning, is the process by which a single gene, or segment of DNA, is isolated and amplified. Recombinant DNA is also known as in vitro recombination. A cloning vector is a DNA molecule that carries foreign DNA into a host cell, where it
A cloning vector is a small piece of DNA that can be stably maintained in an organism, and into which a foreign DNA fragment can be inserted for cloning purposes. [1] The cloning vector may be DNA taken from a virus , the cell of a higher organism, or it may be the plasmid of a bacterium.
