Assessment: WAEC SSCE - Biology - 2005 (Objective) Subject: Biology

Question 1 Report

Which of the following is not a correct base pairing on the DNA strand?
Answer Details
The incorrect base pairing on the DNA strand is Uracil and Thymine. This is because Uracil is found in RNA, not DNA, and it pairs with Adenine instead of Thymine. In DNA, Adenine always pairs with Thymine, and Cytosine always pairs with Guanine. These base pairs are important for maintaining the structure and stability of the DNA molecule, which is essential for proper functioning of our cells.
