Genetic engineering advances have enabled which types of studies?

• A. Elucidating the function of specific genes
• B. Developing animal models for human genetic diseases
• C. Tailoring drugs to a particular patient
• D. All of the above

Answer: (D)

Genetic engineering gives us direct ways to manipulate genes and observe the consequences, which expands what we can study in multiple dimensions. By turning genes off, modifying their expression, or attaching markers, we can pinpoint what a specific gene does and how it fits into cellular pathways. This lets us elucidate the function of particular genes with clearer cause-and-effect evidence. At the same time, it enables the creation of animal models that carry human disease mutations or calibrated edits. These living systems let us watch disease development and test potential treatments in a whole-organism context, which is often essential for translating findings to humans. It also supports tailoring therapies to individuals. Using genetic information and patient-derived cells or organoids for drug screening, along with gene-editing approaches to correct mutations or design targeted interventions, helps move toward more personalized treatment strategies. Because genetic engineering makes all three of these approaches possible, all of these study types are enabled.
