Molecular cloning is a set of experimental methods in molecular biology that are used to assemble recombinant DNA molecules and to direct their replication within host organisms. [1] The use of the word cloning refers to the fact that the method involves the replication of one molecule to produce a population of cells with identical DNA molecules.

Recombinant DNA (rDNA), or molecular cloning, is the process by which a single gene, or segment of DNA, is isolated and amplified. Recombinant DNA is also known as in vitro recombination . 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.
The choice of vector for molecular cloning depends on the choice of host organism, the size of the DNA to be cloned, and whether and how the foreign DNA is to be expressed. [7] The DNA segments can be combined by using a variety of methods, such as restriction enzyme/ligase cloning or Gibson assembly. [citation needed]
The purified DNA can then be used for downstream applications such as PCR, [2] sequencing, or cloning. Currently, it is a routine procedure in molecular biology or forensic analyses. This process can be done in several ways, depending on the type of the sample and the downstream application, [ 3 ] the most common methods are: mechanical ...
The first step in Gateway cloning is the preparation of a Gateway Entry clone. There are a few different ways to make entry clone. Gateway attB1 and attB2 sequences are added to the 5' and 3' end of a gene fragment, respectively, using gene-specific PCR primers and PCR amplification. The PCR amplification products are then mixed with a propriet
Social media influencers are at the center of a growing debate over pet cloning, a special science that uses technology to clone animals. NBC’s Jacob Ward reports for TODAY on how it works to ...
Researchers report the world's first artificial synthesis of starch. The material essential for many products and the most common carbohydrate in human diets was made from CO 2 in a cell-free process and could reduce land, pesticide and water use as well as greenhouse gas emissions while increasing food security.
