Biology Question on Biotechnology
Which of the following cut the DNA from specific places
A
Restriction endonuclease (EcoRI)
B
Ligase
C
Exonuclease
D
Alkaline phosphate
Answer
Restriction endonuclease (EcoRI)
Explanation
Solution
The enzyme that cuts DNA from specific places is Restriction endonuclease, often represented by examples such as EcoRI. These enzymes recognize specific DNA sequences and cleave the DNA at or near those recognition sites. This property is widely used in molecular biology techniques such as DNA cloning and genetic engineering to precisely manipulate DNA fragments. So, the correct option is (A): Restriction endonuclease (EcoRI)
