B. C with C, and G with G
C. C with T, and G with A
D. C with A, and G with T​

Answer 1

A. C with G, and A with T

Step-by-step explanation:

Like proteins, nucleic acids are long chains molecules. The nucleotides are linked through condensation so that the phosphate and the sugar residue form the chain with the organic bases projecting outwards.

The organic bases in DNA are adenine, guanine, thymine and cytosine.The linking is such that guanine always links with cytosine while adenine links with thymine. Guanine is complementary to Cytosine and Thymine is complementary to Adenine.
