What is the end product obtained after exonuclease activity ?

Explanation

**Step-by-Step Solution:**

1. **Understanding Exonuclease**: Exonuclease is an enzyme that plays a crucial role in the breakdown of nucleic acids, specifically DNA.

2. **Function of Exonuclease**: The primary function of exonuclease is to cleave or cut nucleic acid chains. It does this by removing nucleotides from the ends of the DNA strand.

3. **Cleavage Mechanism**: Exonucleases work by cutting the DNA at the terminal ends, which are the 5' and 3' ends of the DNA molecule. This means that the enzyme acts on the ends of the DNA strand rather than the middle.
