In dna how many hydrogen bonds do you need between c and g

G (guanine) and C (cytosine) undergo a specific hydrogen bonding, whereas A (adenine) bonds specifically with T (thymine, in DNA) or U (uracil, in RNA). The GC pair is bound by three hydrogen bonds, while AT and AU pairs are bound by two hydrogen bonds.

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.

i believe it would be c: tons.
