Answer:
- restriction enzymes
- DNA ligase
Explanation:
in recombinant DNA experiments, __restriction enzymes__ is used to cut pieces of DNA, and __DNA ligase_ joins these segments.
- Restriction enzymes are DNA-cutting enzymes that recognize one or a few target sequences and cut the DNA at or near those sequences. (Khan Academy)
- DNA ligase is a DNA-joining enzyme that matches the ends of DNA and joins them to form a single, unbroken molecule of DNA. (Khan Academy)
