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

The genetic material in a cell is DNA. Hence, the first step in genetic engineering is the isolation of genetic material. A cell is treated with lipase, protease and cellulase so that all other components except the nucleic acid is removed.
