Which type of noncovalent interaction supports the double helix of DNA, and produces the base pairings A-T and G-C?

a. ion-dipole interactions
b. dipole-dipole forces
c. ion-ion interactions
d. london dispersion forces
e. hydrogen bonding

Answer :

DNA's double helix is supported by hydrogen bonds, which also provide the base pairings A-T and G-C.

When the DNA helix is split apart for replication, and two strands stable?

Topoisomerases (red) (red) minimize torsional strain brought on by DNA double helix unwinding; DNA helicase (yellow) breaks hydrogen bonds between complementary base-pairs; single-strand binding proteins (SSBs) stabilize the split strands and stop them from coming back together.

What is the enzyme responsible for dividing the two strands of DNA during replication?

The Enzymes called helicases can modify or bind to nucleic acid or nucleic acid protein complexes. Both DNA and RNA have helicases. Because they convert double-stranded DNA into single-stranded DNA, DNA helicases are necessary for DNA replication.
