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.
