Question

The first step in genetic engineering is

• A. Isolation of protein
• B. Purification of protein
• C. Isolation of genetic material
• D. Isolation of RNA

Answer 1

The correct option is C Isolation of genetic material

Genetic engineering, also called as genetic modification, is the direct manipulation of an organism's genome using biotechnology. It is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species to produce improved or novel organisms. New DNA may be inserted in the host genome by first isolating and copying the genetic material of interest using molecular cloning methods to generate a DNA sequence, or by synthesizing the DNA, and then inserting this construct into the host organism.
