In recombinant DNA technology, what is the role of a vector?
Correct Answer: Vectors are DNA molecules that help in transferring foreign genes into host cells.
- Step 1: Understand that a vector is a tool used in genetic engineering.
- Step 2: Know that vectors are usually made from plasmids or viruses.
- Step 3: Realize that the main job of a vector is to carry foreign DNA into a host cell.
- Step 4: Learn that once inside the host cell, the foreign DNA can replicate and express its genes.
- Step 5: Remember that vectors help scientists study genes and develop new treatments.
