cytosine
Cytosine (C) and Guanine (G) pair, as do Adenine (A) and Thymine (T).
Guanine pairs with cytosine in DNA.
Guanine pairs with cytosine in RNA.
guanine
Yes, adenine can pair with guanine in DNA replication through hydrogen bonding.
Cytosine binds [bonds] with Guanine.
guanine
CYTOSINE!
Cytosine
Adenine and Uracil, which pair together (Uracil takes the place of Thymine from DNA) Guanine and Cytosine, which also pair together
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.
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.
