Question

Which of this factor is not responsible for thermal denaturation of DNA?

• A. PH
• B. Temperature
• C. Ionic strength
• D. Humidity

Answer 1

Answer:

D. Humidity

When DNA duplex is laid open to the specific conditions like temperature, pH, or ionic strength it will interrupt the hydrogen bond between strands and they are no longer held together. After denaturation, the strand separates as individual coils and the double helix is denatured.
