DNA Does not contain the following

  • A.Uracil
  • B.Thymine
  • C.Adenine
  • D.Guanine

Answer: A

DNA does not contain Uracil.

The four bases of DNA are adenine, guanine, cytosine and thymine. Uracil is found in RNA, where it takes the place of thymine and pairs with adenine.

Thymine, adenine and guanine are all DNA bases: adenine pairs with thymine and guanine with cytosine in the double helix. So each of the other three options is present in DNA.
