A cloning vector is a DNA molecule that carries foreign DNA into a host cell, where it replicates, producing many copies of itself along with the foreign DNA. There are many types of cloning vectors such as plasmids and phages. In order to carry out recombination between vector and the foreign DNA, it is necessary the vector and DNA to be ...
There are two fundamental differences between the methods. One is that molecular cloning involves replication of the DNA within a living cell, while PCR replicates DNA in the test tube, free of living cells. The other difference is that cloning involves cutting and pasting DNA sequences, while PCR amplifies by copying an existing sequence.
Simpler machines for Taq-based PCR were developed, and on November 19, 1987, a press release announces the commercial availability of the "PCR-1000 Thermal Cycler" and "AmpliTaq DNA Polymerase". In the spring of 1985 John Sninsky at Cetus began to use PCR for the difficult task of measuring the amount of HIV circulating in blood.
A strip of eight PCR tubes, each containing a 100 μL reaction mixture Placing a strip of eight PCR tubes into a thermal cycler. The polymerase chain reaction (PCR) is a method widely used to make millions to billions of copies of a specific DNA sample rapidly, allowing scientists to amplify a very small sample of DNA (or a part of it) sufficiently to enable detailed study.
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 ...
Gibson assembly is a molecular cloning method that allows for the joining of multiple DNA fragments in a single, isothermal reaction. It is named after its creator, Daniel G. Gibson, who is the chief technology officer and co-founder of the synthetic biology company, Telesis Bio.

This is the main advantage of OE-PCR and other long-homology based cloning methods such as Gibson assembly, which overcome the limitations of traditional restriction enzyme digestion and ligation cloning methods. [3] Assembly of custom DNA sequences with OE-PCR consists on three main steps. First, individual DNA sequences are amplified by PCR ...
