Question

How does an alien DNA gain entry into a plant cell by 'biolistics' method?

Answer 1

• Genetic engineering is also known as genetic modification, is a method by which the DNA of an organism is directly manipulated by different methods.
• In bioloistic method, an alien DNA is made to enter the plant cells by high-speed bombardment of gold or tungsten particles.
• In this technique, the DNA-coated particles are propelled by a pressurised gun called the gene gun to introduce the alien DNA into the plant cells.
