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

How do DNA bases match up?
DNA bases match up in a specific way - adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). This is known as complementary base pairing and ensures that DNA strands can replicate accurately.
Adenine is to thymine as guanine is to?
Cytosine. In DNA base pairing, adenine pairs with thymine, while guanine pairs with cytosine. This forms the complementary base pairs that make up the double helix structure of DNA.
How is DNA made up in base pairs?
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.
Which rna base pairs with which DNA strand?
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).
What are the DNA base pairing rules?
Adenine always pairs with thymine Cytosine always pairs with guanine.
What base does adenine pair up with in the DNA?
Thymine, and Cytosine matches with Guanine
What are the fifteen proteins in DNA?
Adanene, Cytosine, Thymene and Guanine. Adanene matches up with Thymene Cytosine matches up with Guanine.

DNA Which base pair up together?
Guanine-Cytosine and Adenine-Thymine
What base does guanine pair whit?
Guanine pairs up with cytosine in both DNA and RNA while adenine pairs up with thymine in DNA only.
Which rna base pairs with which DNA strand?
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).
What does cytosine-guanine mean?
Cytosine and guanine are two of the four nucleotide bases that make up DNA. They are complementary bases that form a base pair, with cytosine always pairing with guanine. This base pairing is essential for the structure and function of DNA.
What are the 4 base pairs of DNA and which bases do they pair up with?
Adenine Guanine Cytosine Thymine This is how i remember it Apples - Teachers Cops- Guns Adenine - Thymine Cytosine - Guanine
What are the DNA base pairing rules?
Adenine always pairs with thymine Cytosine always pairs with guanine.
What are the 4 DNA nucleotides?
The four DNA nucleotides are adenine (A), thymine (T), cytosine (C), and guanine (G). These nucleotides pair up with each other to form the base pairs that make up the DNA double helix.
