NEETZoologyBiotechnology - Principles and Processes
Cloning Vector Features Functions A. Origin of Replication (ori) 1. Helps identify and select transformed cells B. Selectable Marker 2. Controls the copy number of linked DNA C. Cloning Sites 3. Allows insertion of foreign DNA D. Plasmids 4. Replicates independently within bacterial cells
Options
- AA - 2, B - 1, C - 3, D - 4
- BA - 2, B - 3, C - 4, D - 1
- CA - 1, B - 2, C - 4, D - 3
- DA - 3, B - 1, C - 2, D - 4
Correct answer
A. A - 2, B - 1, C - 3, D - 4
Step-by-step solution
The origin of replication (ori) controls the copy number of linked DNA, selectable markers help identify and select transformed cells, cloning sites allow the insertion of foreign DNA, and plasmids replicate independently within bacterial cells.
