Answer to Open Response Question
20. A = G1 of interphase = cell growth (increase in amount of cytoplasm, # of organelles and
increase protein production), regular metabolic activity (cell performs normal cellular functions
through chemical reactions – protein & lipid synthesis, cellular respiration [ATP], enzyme
production [protein synthesis], etc.).
B = S of interphase = DNA replication; amount of DNA/chromatin is duplicated.
C = G2 of interphase = cell prepares for mitosis and cell division; cell produces necessary
organelles and proteins for mitosis and cell division.
D = cell division, which includes mitosis (nuclear division) and cytokinesis (division of the
cytoplasm and cell).
