Answer: a. During DNA replication, enzymes unwind DNA to provide a template for making identical DNA strands.
Explanation: The purpose of DNA replication is to produce genetically identical DNA molecules.
Replication is the process of copying a double-stranded DNA molecule into two identical daughter DNA. The enzyme known as helicase unwinds the DNA so that each strand will serve as a template for the synthesis of a complementary DNA strand. The. Two identical daughter DNA produced each contains one parent DNA strand and one new complementary strand.

In addition to air and
water, our body constantly needs regular inflow of food, which provides the
energy reserves necessary for movement, breathing, thermoregulation, heart,
blood circulation and brain activity. In the process of digestion of food
decays to individual glucose molecules which then fall through the intestinal
wall into the bloodstream. With blood flow glucose transported to the liver,
where it is filtered and delayed in reserve. The pituitary gland supplies the
pancreas and thyroid glands signal to the release of hormones that cause the
liver to throw out the accumulated glucose in the bloodstream, and then
delivers it to the blood to the organs and muscles that are in need of it. Having achieved the
desired body glucose molecules penetrate into the cells, where it is converted
into a source of energy that is available for use by cells. Thus, the process
of continuous energy supply agencies depends on the level of glucose in the
blood.
Taiga is the largest continental biome. It experiences long, cold winters; short, mild summers; and low precipitation. It is characterized by coniferous forests. Taiga covers most of Canada and Siberia. Taiga is not found in the Southern Hemisphere
