What is the name of the temperature that causes two complementary DNA strands to separate?
A
Annealing Temperature
B
Melting Temperature
C
Dissolving Temperature
D
Separation Temperature
Verified step by step guidance1
Understand that the question is asking about the specific temperature at which two complementary DNA strands separate, which is a key concept in molecular biology.
Recognize that DNA strands are held together by hydrogen bonds between complementary bases, and these bonds can be disrupted by increasing temperature.
Identify that the term used to describe the temperature at which half of the DNA molecules in a sample become single-stranded is known as the 'Melting Temperature' (Tm).
Differentiate between the given options: 'Annealing Temperature' refers to the temperature at which single-stranded DNA binds to complementary sequences, 'Dissolving Temperature' and 'Separation Temperature' are not standard terms in this context.
Conclude that the correct term for the temperature causing DNA strand separation is 'Melting Temperature'.
