Question

Which of the following is correctly matched?

A	Agrobacterium tumefaciens	1	Enzyme
B	Taq DNA polymerase	2	Molecular Scissors
C	pBR322	3	Tumour
D	Ligase	4	PCR
E	Hind III	5	Plasmid vector

• A. A- 1, B- 3, C- 2, D- 4, E- 5
• B. A- 3, B- 4, C- 2, D- 1, E- 5
• C. A- 3, B- 4, C- 5, D- 1, E- 2
• D. A- 1, B- 4, C- 5, D- 3, E- 2

Answer 1

The correct option is C A- 3, B- 4, C- 5, D- 1, E- 2

• Agrobacterium tumefaciens is a tumor-inducing organism that carries Ti plasmid.
• Taq DNA polymerase is an enzyme used in polymerase chain reaction for the polymerization of nucleotides.
• pBR322 is a plasmid vector.
• Ligase is an enzyme that helps in binding DNA by forming the phosphodiester bond.
• Hind III acts as molecular scissors as it is a type of restriction endonuclease which cleaves the DNA strands at a specific recognition site.
• So, the correct answer is 'A- 3, B- 4, C- 5, D- 1, E- 2'
