Guanine pairs up with cytosine in both DNA and RNA while adenine pairs up with thymine in DNA only.
Guanine pairs with Cytosine.
I think it pairs with Cytosine.
cythosine
Cytosine, a pyrimidine (sugar) base, pairs with Guanine, a purine (nitrogen) base.
Guanine
Cytosine binds [bonds] with Guanine.
Guanine pairs with cytosine
Guanine
thymine
Cytosine (C) and Guanine (G) pair, as do Adenine (A) and Thymine (T).
Guanine goes with Cytosine
Thymine can only pair with adenine and guanine can only pair with cytosine due to the base-pairing rule.
In DNA,adenine----------thyminecytosine----------guanine
It is not a DNA base pair itself, it is a DNA nucleotide base. It does however, form a base pair when bonded with adenine.
Cytosine is the complement of guanine. no surprise
