Guanine to Cytosine in DNA Via a triple hydrogen bond for example NH2 donor group bonds to the =O acceptor group on G? Similarly, the two donor groups on G (NH and NH2) match the acceptor groups on C
The NH2 at the top of A would clash with the NH2 on C. You can't form an H-bond with two donor groups and no acceptor. Those two groups would actually get in each other's way, forcing the helix to distort. Also, A has no H-bond donors in the middle or at the bottom. So A and C can't pair.
T and C have a different problem. The top and middle groups of T could potentially h-bond with the complementary groups on C. But the helix would hold T and C too far apart. (The connection between each base and the backbone is the wavy line.) H-bonds can't form if the groups are to far apart from each other.
So this is why G and C have to be pared together
Cytosine pairs with Guanine
Adenine Pairs with Thymine
Guanine
Adenine pairs with Thymine
Cytosine pairs with Guanine
Guanine
Guanidine.
Adenine (A) always matches up with thymine (T) and cytosine (C) always matches up with guanine (G).
There are four nucleotide bases that pair up to form the "ladder rungs" that we see on a DNA molecule. These are adenine, thymine, guanine, and cytosine. Adenine matches with thymine, and guanine matches with cytosine. The opposite of each case also occurs (thymine will bind to adenine, and cytosine to guanine).
DNA is made up of two strands. Each strand has one of four bases on it. These are adenine, thymine, guanine and cytosine. On the other strand will be a matching pair. Adenine will match up with thymine and guanine will match up with cytosine. To make it easier, we just say A matches with T and G matches with C. On RNA "T" or thymine is replaced by uracil "U". In this case everything remains the same except now U matches up with A.
4 nitrogenous bases make up a DNA. Cytosine,Guanine ,Thymine,& Adenine T goes with A C goes with G they are base pairs.
DNA and RNA are nucleic acids. When broken to the smallest unit it is called a nucleotide. The nucleotide of both DNA and RNA is up of a sugar molecule which is attached to a phosphate group and a base. The bases of DNA are thymine, adenine, guanine, and cytosine. In RNA adenine is replace with uracil while it keeps thymine, guanine, and cytosine. In DNA adenine pairs with thymine, and cytosine pairs with guanine. In RNA uracil pairs with thymine, and cytosine pairs with guanine.
Thymine, and Cytosine matches with Guanine
Adanene, Cytosine, Thymene and Guanine. Adanene matches up with Thymene Cytosine matches up with Guanine.
Adenine (A) always matches up with thymine (T) and cytosine (C) always matches up with guanine (G).
Guanine-Cytosine and Adenine-Thymine

Guanine pairs up with cytosine in both DNA and RNA while adenine pairs up with thymine in DNA only.

List the nitrogen bases in dna?what happens to chromosomes during the stage of the cell cycle in which the nucleus divides.include the terms prophase, metaphase,anaphase and telophase.one section of a strand of DNA has the base sequence on the other strand?
cytosine pairs with guanine to help make up DNA.
