Study Notes
Restriction System in Bacteria
- Restriction endonucleases defend bacteria against foreign DNA by cutting it into smaller pieces, preventing its replication.
Gene Cloning
- A vector is a small, self-replicating DNA molecule that carries a foreign gene into a host cell, allowing it to replicate and express the gene.
- The purpose of a vector is to act as a carrier of the foreign gene, enabling its introduction and expression in a host cell.
Restriction Endonucleases' Action
- Restriction endonucleases cleave the incoming DNA at specific recognition sites, producing fragments with sticky ends.
Vector Replication and Host Cell Division
- After vector replication, the host cell divides, and the vector is passed to daughter cells, ensuring the continued presence of the foreign gene.
