Cloning vector - Wikipedia
The essence of cell chemistry is to isolate a particular cellular component and then analyze its chemical structure and activity. In the case of DNA, this is feasible.
Plasmids Are Extrachromosomal Self-Replicating DNA Molecules
A cloning vector is a small piece of DNA, taken from a virus, a plasmid, or the cell of a higher organism, that can be stably maintained in an organism, and into.
Description:Four distinct DNA fragments, depicted in different colors, are inserted into plasmid cloning vectors, yielding a mixture of recombinant plasmids each containing a single DNA fragment. Since these enzymes cleave DNA within the molecule, they are also called restriction endonucleases to distinguish them from exonucleases, which digest nucleic acids from an end. The cloned gene may be transferred from a specialized cloning vector to an expression vector, although it is possible to clone directly into an expression vector. These may include a promoter , the correct translation initiation sequence such as a ribosomal binding site and start codon , a termination codon , and a transcription termination sequence. Gene expression however may also be constitutive i. Diagram of a simple cloning vector derived from a plasmid, a circular, double-stranded DNA molecule that can replicate within an E. In this TOPO cloning method a linearized vector is activated by attaching topoisomerase I to its ends, and this "TOPO-activated" vector may then accept a PCR product by ligating both the 5' ends of the PCR product, releasing the topoisomerase and forming a circular vector in the process.
