Question

When a molecule is heated, hydrogen bonds break readily. How will this affect DNA if it is heated?

• A. The DNA will separate into individual nucleotides
• B. The sugars will separate from the phosphates
• C. The DNA will separate into two single stranded sections
• D. The DNA will remain intact

Answer 1

The correct option is A The DNA will separate into individual nucleotides

When DNA molecule is heated, the hydrogen bonds between the strand will be broken separating them into two individual strands.

So, the correct answer is 'The DNA will separate into individual nucleotides'
