9. Which statement about complementary base pairing is not true?a. It plays a role in DNA replication.b. In DNA, T pairs with A.c. Purines pair with purines, and pyrimidines pair with pyrimidines.d. In DNA, C pairs with G.e. The base pairs are of equal length.

There are four different bases in DNA, which always pair up in a particular way. Which of the following shows the correct complementary base pairing? A-X and G-CT-A and G-CA-A, C-C, T-T and G-GA-G and T-C

Which of the following statements about DNA is incorrect?ANSWERThe alternating sugars and phosphate molecules of the DNA backbone bond together via phosphodiester bonds.DNA is a long, single-stranded molecule that curves into a helix, and the set pairings of the bases ensure that there is always a purine across from another purine and a pyrimidine across from another pyrimidine.The nitrogen base adenine always pairs with thymine, and guanine always pairs with cytosine.DNA has an antiparallel arrangement.
