Question

One of the strands of double stranded DNA has base composition as follows: 15% A, 15% T, 40% G and 30% C. What will be the percentage of these bases in the complementary strand?

Accepted Answer

According to the text, the two strands of DNA are complementary to each other due to specific base pairing: Adenine (A) pairs with Thymine (T), and Guanine (G) pairs with Cytosine (C) . Therefore, the percentage of bases in the complementary strand will be determined by the original strand:
- 15% A in the original strand pairs with 15% T in the complementary strand.
- 15% T in the original pairs with 15% A in the complementary.
- 40% G in the original pairs with 40% C in the complementary.
- 30% C in the original pairs with 30% G in the complementary.
Thus, the complementary strand has 15% A, 15% T, 30% G, and 40% C .
