Guanine pairs up with cytosine in both DNA and RNA while adenine pairs up with thymine in DNA only.
Cytosine (C) and Guanine (G) pair, as do Adenine (A) and Thymine (T).
Guanine
The guanine-cytosine base pair is harder to break than the adenine-thymine base pair due to the presence of three hydrogen bonds between guanine and cytosine, compared to two hydrogen bonds between adenine and thymine. This makes the guanine-cytosine pair more stable and stronger.
Cytosine binds [bonds] with Guanine.
Cytosine, a pyrimidine (sugar) base, pairs with Guanine, a purine (nitrogen) base.
Guanine
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 base pairs with cytosine in RNA through three hydrogen bonds.
Guanine goes with Cytosine
Cytosine always pairs with guanine in DNA through hydrogen bonding, forming a stable base pair. This complementary base pairing is a key feature in the double-stranded structure of DNA.
Guanine and cytosine because they are held together by three hydrogen bonds while adenine and thymine are held together by 2.
Guanine will pair with cytosine through three hydrogen bonds in DNA and RNA.
