	Parameter	PCR	Gene cloning
1	Efficient	More	Less
2	Apparatus Requirement	DNA	Restriction enzyme, ligase, vector, bacterial cell
3	Manipulation	In vitro	In vitro and in vivo
4	Cost	More	Less
5	Automation	Yes	No
6	Error probability	Less	More
7	Time for a typical experiment	2-4 days	4 hours
8	Application	More	Less

• A. 1 and 3
• B. 4 and 6
• C. 4 and 7
• D. 4, 7 and 8

Answer 1

Answer: (C)

4 and 7

The cost of gene cloning is far more than PCR because gene cloning requires many intricate steps. PCR takes less than 4 hours while gene cloning can take days.
