Adenine pairs with Thymine
Guanine pairs with Cytosine
The order of the bases in each new DNA molecule exactly matches the order in the original DNA molecule by bringing them together with the original DNA cells.
AT and GC
D
In DNA, the bases that pair together are adenine (A) with thymine (T), and cytosine (C) with guanine (G).
The base of the nucleotides
Base Pair
guanine-cytosine
A DNA molecule may have the same percentage of guanine and cytosine because they bond together through three hydrogen bonds, forming a stable base pair. This complementary pairing ensures that the total percentage of guanine always equals the total percentage of cytosine in a DNA molecule, known as Chargaff's rule.
Each new DNA molecule has an identical base-pair pattern as the original DNA molecule due to the semiconservative nature of DNA replication. This means that one strand of the original DNA molecule serves as a template for the synthesis of a new complementary strand during replication, resulting in two daughter DNA molecules with identical base sequences.
Guanine-Cytosine
Describe how each of the DNA nitrogen bases pair together
In a DNA molecule cytosine always pairs with guanine, the same is true for an RNA molecule.
