Understand the Problem

The question is asking which DNA strand model displays bases that are complementary to those on a student's DNA model. To solve this, we need to identify the base pairing rules for DNA (A with T, C with G) and compare the options provided.

Answer

A

The final answer is A.

Answer for screen readers

The final answer is A.

More Information

In DNA, adenine pairs with thymine, and cytosine pairs with guanine. Model A with bases C, T, A, C, G, A pairs with G, A, T, G, C, T respectively, making it the complementary strand.

Tips

A common mistake is confusing RNA base pairing with DNA base pairing. Remember that in DNA, adenine pairs with thymine, not uracil.
