Question
Biology Question on Molecular Basis of Inheritance
Restriction endonucleases
A
Are used in genetic engineering for ligating two DNA molecules
B
Are used for in vitro DNA synthesis
C
Are synthesized by bacteria as part of their defense mechanism
D
Are present in mammalian cells for degradation of DNA when the cell dies
Answer
Are synthesized by bacteria as part of their defense mechanism
Explanation
Solution
Restriction endonucleases are often referred to as "molecular scissors" due to their unique ability to precisely cut DNA at specified locations in the field of genetic engineering.
