Creating a transgenic model involves several steps: 1. Gene Cloning: The gene of interest is cloned into a suitable vector. 2. Microinjection: This gene construct is then microinjected into fertilized eggs. 3. Implantation: The injected eggs are implanted into a surrogate mother, resulting in the birth of transgenic offspring. 4. Screening: Offspring are screened for the presence of the transgene.
