Answer:
Cytokinesis
Explanation:
All living cells undergo division, it is the method employed in duplicating themselves. The division of cells involves two major processes viz; karyokinesis and cytokinesis.
Karyokinensis involves the division of the genetic material (DNA) in the nucleus. The chromosomes are initially separated into opposite poles/ends inside the cell. After which the cytoplasm of the whole cell then separates resulting in two daughter cells each having its own genetic material. This process is called CYTOKINESIS.
Although CYTOKINESIS occurs in all eukarotes and prokaryotes, the way it occurs in the eukaryotic plant and animal cells differ in the sense that, in animals, it occurs with the formation of a cleavage furrow as a result of pinching inward of the cell membrane until the two daughter cells form while in plants, a cell plate is formed at the cell's centre and a new membrabe and cell wall is formed around each cell plate.
Answer/Explanation:
The replication of DNA is semi-conservative, as each new molecule of DNA inherits one of the parental strands each, and one new strand each. DNA is replicated using the enzyme DNA polymerase, which synthesises a new strand by adding nucleotides in a sequence through complementary base pairing with the template strand. This occurs before the mitosis stage of the cell cycle, where the cell divides. Before this cell division happens, the cell has to pass certain checkpoints controlled by enzymes which ensure environmental conditions are optimal for dividing, and that the new DNA is free from errors.
D I believe but im not sure
