In simple terms, we can define genetic engineering as a laboratory technique used by scientists to change the DNA (Deoxy ribo Nucleic Acid) of living organisms. This exciting branch of engineering or science allows the human minds to interfere in and modify the processes of life, birth death and even offers escape from some congenital diseases. There is huge potential in this field as the demand for genetic engineers is increasing both in India and abroad.
Genetic engineers/scientists re-arrange the sequence of DNA in gene using various artificial techniques. The procedure involves extracting the DNA out of one organism, changing it using chemicals or radiation and then putting it back into the same or a different organism. For e.g.: genes and segments of DNA from one species is taken and put into another species. This branch of science also involves the study of how traits and characteristics are transmitted through the generations, and how genetic disorders are caused. Their research includes researching the causes and discovering potential cures if any.
