Restriction endonuclease:
A
cuts the DNA molecule randomly
B
cuts the DNA molecule at specific sites
C
restricts the synthesis of DNA inside the nucleus
D
synthesizes DNA
Answer
cuts the DNA molecule at specific sites
Explanation
Solution
Restriction endonucleases, also known as restriction enzymes, are enzymes that cleave DNA at specific recognition sequences or sites. These recognition sequences are typically palindromic sequences, and restriction enzymes cut the DNA at or near these specific sites. This is a fundamental tool in molecular biology and genetic engineering for manipulating DNA molecules.
So, the correct option is (B): cuts the DNA molecule at specific sites
