Dna cloning

Gene Cloning- Requirements, Principle, Steps, Applications. It is the production of exact copies of a particular gene or DNA sequence. Gene Cloning Steps.

Process of Recombinant DNA Technology is the technique used for making artificial DNA by genetic modification using multiple sources. Process of Recombinant DNA Technology involves extraction of gene followed by cleaving it at special sites. Then it is put in a molecular vector for its setup in host. At last we need an expression system on which vector along with gene of interest is introduced for multiple copies.

Restriction Endonucleases enzymes that cleave DNA molecules at specific nucleotide sequences depending on the particular enzyme used. Enzyme recognition sites are usually 4 to 6 base pairs in length. Generally, the shorter the recognition sequence, the greater the number of fragments generated.

This diagram gives an overview of DNA cloning.

DNA cloning in a plasmid vector permits amplification of a DNA fragment‼️ A fragment of DNA to be cloned is first inserted into a plasmid vector containing an ampicillin-resistance gene (ampr). Only the few cells transformed by incorporation of a plasmid will survive on ampicillin-containing medium. In transformed cells, the plasmid DNA replicates and segregates into daughter cells, resulting in the formation of an ampicillin-resistant colony in which each cell contains the cloned DNA…

To clone a stretch of DNA (such as a gene) into a vector, restriction enzymes are used to cut out the DNA of interest and to open up the vector. The DNA is added to the vector by mixing the two together in the presence of the enzyme DNA ligase.

DNA cloning is a method used to produce multiple identical copies of a DNA fragment within a cell. DNA cloning is also known as gene cloning or molecular cloning. All ... Read more The post DNA Cloning: Principle, Steps, Components, Methods, Uses appeared first on Microbe Notes.
