Highest melting temperature
WebPopular answers (1) Generally speaking, for optimal results you want your primers to have a melting temperature between 50-60°C. If you have high melting temperatures ( >65°C) you run the risk ... WebExplanation: In the absence of nucleators water can exist as a supercooled liquid down to −48.3 °C (−54.9 °F; 224.8 K) before freezing. The chemical element with the highest melting point is tungsten, at 3,414 °C (6,177 °F; 3,687 K); this property makes tungsten excellent for use as filaments in light bulbs.

WebThus the melting temperature of DNA is influenced by it's GC content. This can also be shown graphically (figure). As per the above figure, you can see two melting curves. As we know higher the GC content of DNA, higher will be the melting temperature. So the first DNA sequence which is GC-rich and the second DNA sequence is not GC rich.
