Genetic Engineering Purpose

The intentional alteration of an organism's genetic makeup to enhance or modify its traits.

Bovine Somatotropin Source

A hormone produced in the pancreas of cattle, responsible for growth and development.

Particle Gun in Genetic Engineering

Directly exposing cells to tiny particles coated with DNA, which then enter the cell.

Safety of Genetically Altered Organisms

Genetically altered organisms are carefully monitored and regulated to ensure their safety and minimize potential risks.
