Wildlife volunteering is a broad topic and there really is something for everyone. Some projects involve really getting your hands dirty in the jungle, but if this does not sound like your thing there are also plenty of other ways to get involved.
EXPERIMENT 2: Recrystallization and Melting Point. Melting Point is: â¢a constant physical property of a solid (the temperature at which it turns to a liquid) â¢reported in the lab as a melting point range (usually 1â2 ËC wide), not as a single temperature.
They cannot anneal to the strand of DNA at temperature 95 degrees centigrade, so the test tube is cooled to 45 - 60 degrees C. The temperature of this step depends on the melting temperature of the primer-template hybrid.
