Name the enzyme which can do proof reading during DNA synthesis in bacterial cells.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the name of the enzyme responsible for proofreading during DNA synthesis in bacterial cells.

2. **Role of DNA Synthesis**: During DNA synthesis, new DNA strands are formed from existing templates. This process can sometimes lead to errors, such as the incorporation of incorrect nucleotides.

3. **Importance of Proofreading**: Proofreading is a critical mechanism that ensures the accuracy of DNA replication. If errors are not corrected, they can lead to mutations, which may result in defective proteins and various disorders.
