Answer:
The most basic function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells.

Answer:
Beginning the age of European exploration
Explanation:
The main function of the mitochondria is respiration in the cell. To produce energy from broken down organic molecules. (i.e. carbohydrates.)
The myosin head separates from actin as a result of ATP binding. The intrinsic ATPase activity of myosin then transforms ATP into ADP and Pi. The myosin head's angle is altered into a cocked state by the energy generated during ATP hydrolysis. The myosin head is now ready to move in the future.
The myosin protein is in a high-energy conformation when the head is cocked. At the end of the power stroke, the myosin head is in a low-energy position because this energy has been used up during the power stroke. ADP is released following the power stroke, but the cross-bridge is still there and actin and myosin are joined together.
Since ATP is readily available, the cross-bridge cycle can repeat, and muscular contraction can go on as long as ATP is there.

The property of DNA which causes it to migrate to the positive pole of the electrophoresis apparatus is B. the negative charge of the DNA.
It acts just like a magnet - positive and negative forces attract.
