Question

The given figure is the diagrammatic representation of the E. coli vector pBR322. Which one of the given options correctly identifies its certain component (s) ?

A. Ori-original restriction enzyme
B. rop-reduced osmotic pressure
C. Hind III, Eco RI-selectable markers
D. `amp^(R ) tet^(R )` - antibiotic resistance genes

Answer 1

Correct Answer - d
Ori represents the site of origin of replication, rop represents the proteins that take part in the replication of plasmid. Hind III, Eco RI are the recognition sites of restriction endonucleases and `amp^( R) and tet^(R )` are the antibiotic resistant genes.
