Question

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

विकल्प

• Ori - original restriction enzyme

• rop - reduced osomotic pressure

• Hind III, EcoRI - selectable markers

• amp^R, tet^R- antbiotic resistance genes

Answer 1

amp^R, tet^R- antbiotic resistance genes

Explanation:

In pBR322,

• Ori - represents origin of replication.
• rop - codes for proteins that take part in replication of plasmid.
• Hind III, EcoRI - recognition sites or restriction endonucleases.
• amp^R tet^R - antibiotic resistance genes.
