If the DNA macromolecule contains 20% G (guanine), then by Watson-Crick complementarity it must contain 20% C (cytosine). Together this equals 40%, so the percent that is A (adenine) and T (thymine) together is 60%. By Watson-Crick complementarity, then, the percent A in the molecule is half of 60: 30%.
there is 20% t, so there should be 20% a
60% is leftover for g and c, so you divide it
and it would be 30% g and 30% c
the answer is 30&
30 percent 30 percent
30 % guanine

In a DNA molecule cytosine always pairs with guanine, the same is true for an RNA molecule.
guanine cytosine thymine adenine (an RNA molecule replaces thymine with uricel)
The two bases that are present in equal amounts in a double stranded DNA molecule are cytosine and guanine. Cytosine pairs with guanine in A DNA molecule.
Cytosine is always coupled with Guanine. (I like to remember that the round letters stick together).In DNA, Thymine is coupled with Adenine, but in RNA, Thymine is replaced by Uracil.Therefore, in RNA, U and A go together, always.
Adenine, Thymine, Cytosine, and Guanine. Adenine pairs with Thymine (A-T), and Cytosine pairs with Guanine (C-G). In an RNA molecule, Thymine is replaced by Uracil, so it would be Adenine and Uracil (A-U) and Cytosine and Guanine (C-G).
Guanine bonds to Cytosine in DNA through three hydrogen bonds. It also bonds to a Deoxyribose molecule in the backbone of the DNA molecule.

Adenine, Thymine, Guanine, and Cytosine
The two bases that are present in equal amounts in a double stranded DNA molecule are cytosine and guanine. Cytosine pairs with guanine in A DNA molecule.
DNA contains adenine, thymine, guanine, and cytosine.
The four bases in RNA are Cytosine, Guanine, Adenine and Uracil
In a DNA molecule cytosine always pairs with guanine, the same is true for an RNA molecule.
Cytosine is always coupled with Guanine. (I like to remember that the round letters stick together).In DNA, Thymine is coupled with Adenine, but in RNA, Thymine is replaced by Uracil.Therefore, in RNA, U and A go together, always.
