Denaturation of double stranded DNA involves_______________?

Correct answer: B. It becomes single stranded reversibly

  • A. It gets broken down to nucleotides
  • B. It becomes single stranded reversibly
  • C. It becomes single stranded irreversibly
  • D. It becomes double stranded irreversibly

Explanation

Denaturation separates the two complementary DNA strands by disrupting hydrogen bonds, without breaking the covalent backbone. The strands can reassociate when suitable conditions are restored, so the process is reversible.
