Final answer:
The melting temperature, or Tm, of DNA fragments can be calculated using their sequences, but the specific sequences of the fragments are needed for calculation.
Step-by-step explanation:
The melting temperature, or Tm, of DNA fragments can be calculated using the sequences of the fragments.
The Tm provides an indication of how tightly the DNA strands are able to bind to each other.
The Tm is influenced by factors such as the G = C content of the DNA, with higher G = C content resulting in a higher Tm.
Unfortunately, without the specific sequences of the DNA fragments in question, it is not possible to calculate the melting temperature.
