LIFE SCIENCE

Detailed explanation-1: -DNA cloning either through the use of cloning vectors or the polymerase chain reaction, whereby a single DNA molecule can be copied to generate many billions of identical molecules.

Detailed explanation-2: -Cloning is a technique scientists use to make exact genetic copies of living things. Genes, cells, tissues, and even whole animals can all be cloned.

Detailed explanation-3: -DNA Cloning: Biotechnology cloning techniques used to create many copies of DNA fragments are called as DNA cloning. This technique can be used to clone random fragment of DNA, specific sequence of DNA or can be used to clone entire gene sequence.

Detailed explanation-4: -Recombinant DNA technology involves using enzymes and various laboratory techniques to manipulate and isolate DNA segments of interest. This method can be used to combine (or splice) DNA from different species or to create genes with new functions. The resulting copies are often referred to as recombinant DNA.
