Heating a piece of DNA can denature it, just as it does to a protein. In the case of DNA, the loss of secondary structure leads to the separation of the strands. Would a piece of DNA that is “AT-rich” separate at a lower or higher temperature than a piece of DNA that is “GC-rich?” Why? 8. Polymerization of nucleic acids utilizes nucleoside triphosphates.
