Final answer:
Inducible transgenic models are activated under specific conditions or in response to an inducer, while conditional transgenic models allow researchers to control gene expression at specific times or in specific tissues.
Step-by-step explanation:
Inducible and conditional transgenic models are both used in genetic research to study gene expression. Inducible transgenic models are created by introducing a gene that is only activated under specific conditions or in response to an inducer molecule. For example, the lac operon in bacteria is inducible because the gene for lactose metabolism is only turned on when lactose is present. On the other hand, conditional transgenic models involve the use of genetic techniques to control the expression of a specific gene at specific times or in specific tissues. This can be achieved by introducing a gene that produces a protein that can activate or inhibit the expression of the target gene. Conditional transgenic models allow researchers to study the effects of gene expression in a controlled and precise manner.
