Gene Splicing What Is It? Gene Splicing is one type of genetic technology. It is the process of taking pieces of DNA from one or more organisms then combining them into another DNA strand to create new DNA or recombinant DNA. How does it Work? Chemicals called restriction enzymes are used as scissors to cut the DNA. Thousands of these restriction enzymes exist‚ each recognizing only a single sequence of DNA. Once it finds that sequence in a strand of DNA‚ it attacks it and splits the base pairs
