Can you list options since its which of the following?
Answer:
c. If the double helix were unwound, each nucleotide along the two parent strands would form a hydrogen bond with its complementary nucleotide.
Explanation:
According to the Watson-Crick model, two DNA strands are held together by complementary base pairing wherein each nucleotide of one DNA strand forms hydrogen bonds with its complementary nucleotide present in the other strand. During DNA replication, two DNA strands are separated by the action of helicases enzymes.
The separated DNA strands serve as a template for DNA replication. Here, each nucleotide of the template DNA strand binds to its complementary nucleotide by hydrogen bonds. For example, adenine of the template strand forms two hydrogen bonds with thymine while guanine forms three hydrogen bonds with cytosine.

Extrusive igneous rocks form when lava hardens and cools.
Extrusive igneous rocks are types of igneous rocks that form when hot magma from inside the earth extrudes to the surface as lava which hardens and cools immediately to form small crystals. Some lava can also cool immediately to form an amorphous glass. Examples of extrusive igneous rocks include rhyolite, andesite, obsidian, basalt, pumice, scoria, tuff and dacite.
