Cytosine (C) and Guanine (G) pair, as do Adenine (A) and Thymine (T).
Guanine attaches to cytosine through hydrogen bonding to form a base pair in DNA.
In a DNA molecule cytosine always pairs with guanine, the same is true for an RNA molecule.
Guanine and cytosine because they are held together by three hydrogen bonds while adenine and thymine are held together by 2.
Guanine pairs with Cytosine on the human DNA double helix. Adenine pairs with Thymine.
Guanine base pairs with cytosine in RNA through three hydrogen bonds.
Guanine attaches to cytosine through hydrogen bonding to form a base pair in DNA.
No. Adenine doesn't even usually pair with Cytosine. If you're talking about DNA, Adenine pairs with Thymine and Cytosine pairs with Guanine. A with T, C with G. This is only a general rule, however- Adenine and Cytosine can pair if you have a wobble base pair.
Thymine and guanine cannot pair because they do not form complementary base pairs in DNA. In DNA, adenine pairs with thymine and guanine pairs with cytosine due to hydrogen bonding properties. Thus, thymine and guanine are not complementary bases and cannot form a stable base pair.
Guanine goes with Cytosine
Cytosine is a nitrogenous base that is a component of DNA, but on its own, it is not a nucleotide. In DNA, cytosine pairs with guanine through hydrogen bonding to form a complementary base pair. Nucleotides are composed of a nitrogenous base, a sugar, and a phosphate group.
In a DNA molecule cytosine always pairs with guanine, the same is true for an RNA molecule.
Guanine
Cytosine should not ever pair with thymine, for two major reasons: Cytosine and thymine are both pyrimidines, meaning they contain a single sugar, whereas adenine and guanine are purine and contain a two-ringed sugar. If cytosine were to pair with thymine (or another cytosine) it would throw off the shape of the DNA double helix. Cytosine wants to form three hydrogen bonds, and thymine can only form two. Thus, under normal circumstances, cytosine will never be paired with thymine.
Cytosine binds [bonds] with Guanine.
Guanine and cytosine because they are held together by three hydrogen bonds while adenine and thymine are held together by 2.
Guanine
Guanine pairs with Cytosine on the human DNA double helix. Adenine pairs with Thymine.
