Knockout experiments ______________ genes.a. deleteb. inactivatec. expressd. either a or b

Key Concepts: Knockout Experiments, Genes, Deletion, Inactivation, Gene Expression Explanation: Knockout experiments are a common technique used in genetics to study the function of a particular gene. It involves creating organisms, typically mice, that are missing one or more genes. This is achieved through the deletion or inactivation of the gene in question. Step by Step Solution: Step 1. Knockout experiments are used to study the function of genes. Step 2. Genes can be deleted or inactivated through knockout experiments. Step 3. Therefore, the answer is either a or b, meaning genes can be deleted or inactivated in knockout experiments. Final Answer: either a or b
