Answer 2

Answer:

The science of getting exact copies of desired living organisms is known as cloning.

Explanation:

The process in which a gene of interest is located and copied of all the DNA extracted from an organism.

It is a widely applied technique in the field of DNA and protein research as well as in the field of molecular biology. Various methods are used for gene cloning.

They are:

• Restriction enzyme digestion and ligation.
• Transformation
• Recombinase dependent cloning
• PCR cloning
• TA cloning
• Ligation independent cloning

Basically, gene cloning involves the following steps:

• The gene of interest is that organism's DNA is extracted and cut into the size of genes with the help of restriction enzymes.
• The bacterial plasmids (DNA) are also cut with the same enzyme.
• Both cut DNA and plasmid are kept together in a test tube. Their combination gives rise to recombinant DNA.
• The recombinant DNA is transferred into bacteria using heat shock.
• The bacteria multiply into colonies called gene libraries.
• The gene library is then screened to identify the gene of interest by observing three things on each i.e a sequence of DNA similar to the gene of interest, a protein encoded by a gene of interest, a DNA marker with a location close to a gene of interest.
