Cloning of PTEN divisor in to pETBlue-
Describe the strategy that was utilise in the experiment. What is directional cloning
and what atomic number 18 its benefits?
The cloning strategy utilise in this experiment was directional cloning. There are chiefly three steps involved in this type of cloning.
They are amplification of DNA fragmentise containing cistron of interest.
Insertion of gene of interest.
Transfer of the gene of interest.
AMPLIFICATION OF DNA FRAGMENTS: The DNA fragment containing the gene of interest was amplified using the PCR technique (Brown 2006).
INSERTION OF factor OF wager :In this step the gene of interest is inserted in to the vector dna at the limitation site (ECORV).This restriction site is present after the ribosome binding site of t7 promoter, helps to deem effective translation. Ligation takes place in a specific port in which blunt ends and sticky ends are produced in both(prenominal) vector DNA and insert DNA.
TRANSFER OF GENE OF INTEREST: this is the main step involved in the cloning, here the vector DNA i.e.



pETBLUE-1 transfers the gene in to the bacterium, then bemuses replicated into several copies of gene of interest. This gene of interest is expressed by pET BLUE.

DIRECTIONAL CLONING: Directional cloning is delineate as the technique where two restriction enzymes are use for producing heterologous ends in which gene of interest to be ligated is inserted in to the vector in a specific manner which prevents egotism ligation of vector.
Directional cloning of targeted DNA can be achieved that when the ligation of the duplex DNA molecule contains suitable restriction sites (Schoonbroodt.S, et al, 2005) .Benefits of directional cloning includes it does not require kinasing primer phosphatised...If you want to get a full essay, order it on our website: Ordercustompaper.com
