What is the complementary base for guanine?
Cytosine binds with Guanine.
The structure of DNA relies on a base-pairing rule. This means that in DNA, Adenine binds to Thymine and Guanine binds to Cytosine. The complementary base is the base that binds to the base in question. Therefore A is complementary to T, C is complementary to G, etc. So if you had a strand of DNA, for example; ATT-CCA-GTC The complementary strand (which would bind to the above) would be; TAA-GGT-CAG
In DNA complementary base parings are the DNA monomers or bases, Thymine with Adenine (or Uracil and Adenine in RNA) and Guanine with Cytosine. Only these paring occur, the base thymine doesn't complement guanine or cytosine so doesn't pair with it. Thymine with Adenine forms 2 hydrogen bonds and Guanine with Cytosine forms 3 hydrogen bonds (these difference in the number of bonds formed is the reason for the complentary nature).
Guanine, Adenine, Thymine You left out cytosine. The four base pairs in the nucleic acid for DNA are: Adenine, Guanine, Thymine and Cytosine. The four base pairs in a DNA (deoxyribonucleic acid) strand are as follows: Cytosine, Guanine, Adenine and Thymine. They complement each other in DNA as follows: Cytosine = Guanine and Adenine = Thymine This means that if you are given one side of DNA, you will be able to figure out the…
