Final answer:
The sequence of the DNA is TCTA.
Step-by-step explanation:
In pyrosequencing, the graph shows peaks of luminescence that correspond to the addition of nucleotides. By analyzing the peaks in the graph, you can determine the sequence of the DNA. In this case, the peaks are as follows: dT peak, dC peak (double height), dT peak, dA peak.
Based on this information, the sequence of the DNA is TCTA.
