Cloning Vector Components Descriptions A. Ori (Origin of Replication) 1. Essential for DNA replication within the host B. Selectable Marker 2. Allows identification of successful transformations C. Cloning Site 3. Region containing multiple restriction enzyme sites D. Multiple Cloning Site (MCS) 4. Site for the insertion of foreign DNA

Options

  1. AA - 1, B - 2, C - 4, D - 3
  2. BA - 3, B - 1, C - 4, D - 2
  3. CA - 4, B - 3, C - 2, D - 1
  4. DA - 2, B - 4, C - 1, D - 3

Correct answer

A. A - 1, B - 2, C - 4, D - 3

Step-by-step solution

The origin of replication (ori) is essential for DNA replication within the host, selectable markers allow identification of successful transformations, cloning sites are where foreign DNA is inserted, and the multiple cloning site (MCS) contains multiple restriction enzyme sites.
