A Vector DNA is a small piece of DNA containing regulatory and coding sequences of interest. Space-filling model of a section of DNA molecule Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions specifying the biological development of all cellular forms of life (and many viruses). ...
A vector is a DNA molecule into which foreign fragments of DNA may be inserted. A vector functions like a "molecular carrier", which will carry fragments of DNA into a host cell.
Vectors are usually derived from plasmids, which are small, circular, double-stranded DNA molecules occurring naturally in the cytoplasm of bacteria.
Vectors contain an origin of replication, which enables the vector, together with the inserted foreign DNA fragment inserted into it, to replicate.
Vectors contain genetic markers that allow for selectoin of cells which have taken up the plasmid DNA.
Vector DNA functions to insert and amplify a gene into a target genome. This stylistic schematic diagram shows a gene in relation to the double helix structure of DNA and to a chromosome (right). ... In biology the genome of an organism is the whole hereditary information of an organism that is encoded in the DNA (or, for some viruses, RNA). ...
