Question

Predict the effect of increasing temperature on the structure of DNA and RNA molecules?

Answer 1

Increasing temperature causes the structure of DNA and RNA molecules to denature and unravel, but they can re-anneal and reform the double helical structure.

Step-by-step explanation:

Increasing temperature has an effect on the structure of DNA and RNA molecules. Specifically, at higher temperatures, the hydrogen bonds between the bases in the DNA and RNA molecules are disrupted, causing the molecules to denature and unravel. This is known as melting of DNA or RNA. However, when the temperature is brought back to normal biological range, the DNA or RNA strands can re-anneal and reform the double helical structure.
