Restriction enzymes play a crucial role in genetic engineering by recognizing specific sequences of DNA and cutting the DNA at those points. This ability allows for the extraction of useful genes from one organism. When a restriction enzyme cuts DNA, it often creates "sticky ends," which are single-stranded overhangs that can easily bind to complementary sequences on other pieces of DNA. This makes it possible to insert the cut gene into a plasmid or another piece of DNA, facilitating the cloning or modification of genes for various applications.

This process is foundational in recombinant DNA technology, where genes from different sources are combined. The precise cutting of DNA allows for the targeted manipulation of genetic material, which is essential in creating transgenic organisms, producing proteins for medicine, and conducting research in molecular biology. Thus, the correct answer highlights the functional significance of restriction enzymes in isolating genes of interest crucial for various scientific and medical advancements.
