Question

Match column-I with column-II and choose the correct option. Column I Column II

A.EcoRI	I.Bacilius amyloliquefaciens
B.Bam HI	II.Haemophilus influenza
C.Hind III	III.Escherichia coli
D.pBR322	IV.Artificial plasmid

• A. A – III; B – I; C – II; D – IV
  
• B. A – II; B – I; C – IV; D – III
  
• C. A – IV; B – I; C – III; D – II
• D. A – I; B – IV; C – II; D – III

Answer 1

The correct option is A A – III; B – I; C – II; D – IV


EcoRI, Bam HI and Hind III are restriction endonucleases obatines from bacteria.
EcoR1 is extracted from E. coli
Bam H1 is extracted from Bacillus amyloliquifaciens
Hind III is extracted from Haemophilus influenzae

pBR322 is an artificially constructed plasmid with 2 selectable marker regions and several restriction sites.
