The figure below is the diagrammatic representation o the E.Coli vector pBR 322. Which one of the given options correctly identifies its certain components(s)?

Ori- original restriction enzyme

rop-reduced osmotic pressure

Hind III, Eco RI-selectable markers

amp^R , tet^R -antibiotic resistance genes

Solution

amp^R , tet^R -antibiotic resistance genes

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. amp^R and tet^R are the antibiotic resistant gene parts.
