Shuttle vectors are frequently used to quickly make multiple copies of the gene in E. coli (amplification). They can also be used for in vitro experiments and modifications (e.g. mutagenesis, PCR). One of the most common types of shuttle vectors is the yeast shuttle vector. [2] Almost all commonly used S. cerevisiae vectors are
The binary vector is a shuttle vector, so-called because it is able to replicate in multiple hosts (e.g. Escherichia coli and Agrobacterium). Systems in which T-DNA and vir genes are located on separate replicons are called T-DNA binary systems.
The vector itself generally carries a DNA sequence that consists of an insert (in this case the transgene) and a larger sequence that serves as the "backbone" of the vector. The purpose of a vector which transfers genetic information to another cell is typically to isolate, multiply, or express the insert in the target cell.
P1 vectors also contain a P1 plasmid replicon, which ensures only one copy of the vector is present in a cell. However, there is a second P1 replicon- called the P1 lytic replicon- that is controlled by an inducible promoter. This promoter allows the amplification of more than one copy of the vector per cell prior to DNA extraction. [2] bac vector

The space shuttle project was forged in the optimism of NASA’s Apollo program, which landed 12 astronauts on the surface of the moon and bested America’s Soviet rivals during the Cold War.
The two solid rocket motors, each weighing 104,000 pounds and the size of a Boeing 757 fuselage, were trucked from the Mojave Air and Space Port over two days.
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.
