EcoRI cuts the DNA between bases Guanine and Adenine. The sequence for this cut in a DNA should be:

Explanation

To determine the DNA sequence that EcoRI cuts, we need to follow these steps:

### Step-by-Step Solution:

1. **Understand the Function of EcoRI**: EcoRI is a restriction enzyme that recognizes specific DNA sequences and cuts between certain bases. In this case, it cuts between Guanine (G) and Adenine (A).

2. **Identify the Recognition Sequence**: The recognition sequence for EcoRI is known to be a specific pattern of nucleotides. For EcoRI, the sequence is:
- 5' - G A T T C - 3'
