Which of the following statements does not hold true for restriction enzyme ?

Options

A. It recognises a palindromic nucleotide sequence
B. It is an endonuclease
C. It is isolated from viruses
D. It produces the same kind of sticky ends in different DNA molecules.

Explanation

### Step-by-Step Solution:

1. **Understanding Restriction Enzymes**:
- Restriction enzymes, also known as molecular scissors, are proteins that cut DNA at specific sequences. They are crucial for various biotechnological applications, including cloning and genetic engineering.

2. **Function of Restriction Enzymes**:
- These enzymes recognize specific palindromic nucleotide sequences in DNA and cleave the DNA at these sites. This is essential for the defense mechanism in bacteria against foreign DNA, such as that from viruses.
