Cloned strain or line
A strain or line descended directly from a clone.

Cloning
1. The mitotic division of a progenitor cell to give rise to a population of identical  daughter cells or clones.
2. Incorporation of a DNA molecular into a chromosomal site or a cloning vector.

Cloning site.
See insertion site.

Cloning vector
1.A small, self-replicating DNA molecule-usually a plasmid or viral DNA chromosome –into which foreign DNA is inserted in the process of cloning genes or other DNA sequences of interest. It can carry inserted DNA and be perpetuated in a host cell. Also called a cloning vehicle, vector, or vehicle., See vector.

2. A molecule that carries a foreign gene into a host, and allows/ facilitates the multiplication of that  gene in a host. When sequencing  a gene that has been cloned using a cloning vector (rather than by PCR), care should be taken not to include that cloning vector sequence when performing similarity searches. Plasmids, cosmids, phagemids, YACs and PACs are example types of cloning vectors.

Closed continuous culture
A continuous culture in which inflow of fresh medium is balanced by outflow of corresponding volumes of spent medium. Cells are separated mechanically from outflowing medium and added back to the culture. cf open continuous culture; batch culture; continuous culture.
