Short answers:
- create a “perfect” baby — No (not in any realistic sense). Selecting embryos or editing single-gene disease mutations is possible in some contexts, but you cannot reliably engineer complex traits (intelligence, height, personality) into a “perfect” baby. Technical limits, many genes + environment influence, and strong ethical/legal constraints make “designer babies” impractical and widely prohibited.
- produce insulin to treat diabetes — Yes. Recombinant DNA techniques are routinely used to make human insulin in bacteria/yeast; that biotech application is a classic success of genetic engineering.
- replace a person’s missing limb — No (not by genetic engineering today). Limb replacement is done with prosthetics and surgical reconstruction. Regenerative medicine and gene- or cell-based therapies aimed at tissue repair are research areas, but full limb regrowth in humans is not a current capability.
- locate blood at a crime scene — Not really by genetic engineering. Chemical tests (e.g., luminol) detect blood; DNA analysis (PCR, DNA profiling) can identify whose blood it is once you have a sample. DNA testing uses molecular biology techniques but is distinct from “genetic engineering” as commonly understood.
Summary: Of the four, producing insulin is the clear present-day application of genetic engineering; the others are either impossible now, limited, or use related but different techniques.
