How do bases bond together?
Note that adenine only bonds with thymine, and cytosine only bonds with guanine. The nitrogen bases are held together by hydrogen bonds: adenine and thymine form two hydrogen bonds; cytosine and guanine form three hydrogen bonds.
What are the 4 bases in RNA?
The four bases that make up RNA are: * Adenine (A) * Cytosine (C) * Guanine (G) * Uracil (U)
Which of these bases form a true complementary pair?
adenine and guanine
Why Guanine and cytosine have triple bond in between and Adenine and Thymine have double bond in between?
Actually no one knows why it is just Erwin Chargaff's rule of defining DNA.
What bases would match up to form a matching DNA strand from this pattern?
THYMINE-ADENINE CYTOSINE-GUANINE
Why does C always have to bond with G?
C always has to bond with G because of base pairing rules. Only between Cytosine and Guanine are there opportunities to form hydrogen bonds. This is why Adenine or Thymine cannot bond with Guanine and Cytosine.
Which pair of nitrogenous bases will form a bond in a DNA molecule?
Complementary nitrogen bases pair by means of hydrogen bonds. Refer to the related link below for an illustration.

What are the four pairs of DNA that form a double hilix?
I think this is the answer you are looking for: A hydrogen bond forms between the nitrogen bases Adenine (A) and Thymine (T), and between Cytosine (C) and Guanine (G).
How do the 4 bases of DNA pair?
The four different nucleotides have different strucutres: Adenine and Guanine have 2 ring structures. However, Cytosine and Thymine have singular ring structures. This means that Adenine cannot pair with Guanine as the two ring structures will be bigger than the singular ringed structure and the two strands of DNA are equidistant the entire length. Adenine and Thymine both have the ability to form 2 hydrogen bonds, whereas Cytosine and Guanine form 3 hydrogen bonds. Therefore Adenine and Thymine bond together, Cytosine and Guanine bond together. These hydrogen bonds between four different types of nucleotides (due to 4 different nitrogenous bases) hold together the two strands of DNA to form a double strand of DNA.

What two bases form three hydrogen bonds?
cytosine and guanine form three hydrogen bonds between them
Which of these bases form a true complementary pair?
adenine and guanine
If adenine makes up 30 percent of the bases in a DNA helix what percentage of the bases are cystosine?
There are four bases in the DNA double helix: adenine, guanine, cytosine and thymine. An adenine in one strand always pairs with a thymine in the other strand. Similarly, a cytosine always pairs with a guanine. So the number of adenines always equals the number of thymines, and the number of cytosines always equals the number of thymines. The total number of bases must equal 100%. So if 30% of the bases are adenine, another 30% must be thymine because they always pair with each other. Thymine and adenine added together therefore make 60% of the bases. The remaining 40% must be cytosine plus guanine. If the number of cytosines must equal the number of guanines, the percentage of cytosines must be ....... well, you can work it out for yourself!
