It is D. Explanation:Because Cytosine pairs with Guanine, and Adenine pairs with thymine. C with GG with CA with TT with A... Show More
Explanation:In dsDNA the bases in the two strands are paired through hydrogen bonds forming base pairs (bp). Adenine forms two H-bonds with thymine from opposite strand and vice-versa. Similarly, guanine is bonded with cytosine with three H-bonds. As a result, always a purine comes opposite to a pyrimidine.A - T   &   G - C... Show More
C: A with T and C with GExplanation:DNA has four bases and A always pairs with T while C always pairs with G.... Show More
D). T with A, and C with GExplanation: DNA is a nucleic acid found in the nucleus of a cell. It contains all the genetic information of the cell. Nucleic acids are made up of three parts: the nitrogenous base, the ribose sugar and phosphate group. DNA contains deoxyribose sugar. The bases found in nucleic acids are of two types: the pyrimidine and purine bases. The pyrimidine bases are Cytosine, Thymine and Uracil. The purine bases are Adenine and Guanine. In DNA, only two pyrimidine bases can be found: Cytosine and Thymine. In DNA base pairing, Thymine (T) pairs with Adenine (A) while Cytosine (C) pairs with Guanine (G).... Show More
The correct answer would be A.T with A, and C with GIt can be explained with the help of complementary base pairing.In DNA,  thymine (T) always forms a base pair with adenine (A) and cytosine (C) always base pairs with guanine (G) .There are two hydrogen bonds present in between A and T and three hydrogen bonds in between G and C....
