DNA is denatured at ________.

Question

Quizplus · Accepted Answer

DNA denaturation occurs at high temperatures. The temperature at which 50% of DNA strands are denatured is called the melting temperature (Tm). For DNA, the Tm is around 94ᵒC. Therefore option (D) is the correct answer. Options (A) and (B) are lower than the Tm and will not denature DNA significantly. Option (C) is closer but still lower than the Tm. Option (E) is too high and would fully denature the DNA, breaking it down into individual nucleotides.
