What technology is used for genetic engineering?

Could you elaborate, please? Could you provide some insight into the technological advancements that underlie genetic engineering? I'm particularly interested in understanding the specific techniques and tools that are employed in this field. Are there any innovative technologies that are currently being developed or used for genetic engineering? Could you give an example or two of these technologies and explain how they work? I'm fascinated by the potential of genetic engineering and its applications in various fields, so your explanation would be greatly appreciated.
