The Basics of Recombinant DNA Technology
Understanding the fundamentals of recombinant DNA technology helps appreciate its impact.
- Recombinant DNA technology involves inserting a DNA fragment from one organism into the DNA of another.
- Restriction enzymes act like molecular scissors, cutting DNA at specific sequences.
- Ligases are enzymes that glue DNA fragments together.
- Plasmids, small circular DNA molecules found in bacteria, often serve as vectors to carry foreign DNA.
- Transformation is the process of introducing recombinant DNA into a host cell.
Historical Milestones
