DNA-RNA hybrids versus DNA-RNA hybrids

[Christine HANS]

HI ! it's Christina la BOMBA

Would you please give us some informations about nucleic acid hybrids :

- Why are DNA-RNA hybrids more stable than DNA-DNA hybrids (same length,
same composition) ? We need some references.

- What is the effect of bivalent cations on melting temperature and why do
bivalent cations have more influence on Tm than monovalent cations ?
