Discuss how and why the investigative method of molecular genetics has had the greatest impact on human genetics
over the last several decades. What will be an ideal response?
ANSWER: Molecular genetics uses recombinant DNA technology to identify, isolate, and produce
millions of copies of genes (clones) that can be studied in the laboratory. These methods have
greatly advanced our knowledge of how genes are organized and how they work at the
molecular level.
