Gene technology as a tool for biotechnology

Most biotechnology companies make use of gene technology or genetic engineering, which involves recombinant DNA and gene cloning.

More recently, extensive use of newly discovered polymerase chain reaction (PCR) and DNA chips (microarrays) has also been made for gene technology.

The PCR technology and its applications are discussed in and DNA chips are discussed.

This gene technology has become a major thrust area of present day researches and some of the developed countries are encouraging researches in this field as a matter of national priority.
