Mitosis

Define and describe the steps of binary fission

Binary fission in prokaryotic cell division. First the cell copies its DNA, then the cell grows, last the cell splits into two

List and describe the 3 parts of interphase

G1: cell growth one

S: synthesis of DNA (DNA copied)

G2: cell growth two (preparation for division)

Describe the structure of a duplicated chromosome

Two identical sister chromatids held together by a centromere

Suscribe the difference in cytokinesis between plant and animal cells,

Plant cells form a cell plate and splits into two. Animal cells form a cleavage furrow and pinch into two.

List three external factors that play a role in controlling cell division

Growth factors, density of cells, and anchorage dependence.
