Question

2. Match the phase to the description. NOTE: this question might look a little different on the Moodle activity. Read carefully. Phase Hanne Description of Events in the Life of a Cell • Anaphase of muitosis A. The combined phases of GI/Go+S+G2 • Gl phase • G2 phase B. The cell is metabolically active; the cell duplicates argumelles and cytosolie components; the cell size starts to increase the cell makes proteins which will soon be used in DNA synthesis C. The cell has the option of moving out of the divisional phase of the cell cycle and cntering a long-term non-divisional phase, but it can return to the cycle at a later point if needed • Gio phase • Interphase D. DNA is replicated (aka DNA synthesis) Prophase of mitosis • S phase E. The cell makes enzymes and other proteins wbich will soon be used in the M phase; it finishes this phase twice the size it started in GI • Mitosis F. Unreplicated chromosomes hecime replicated, each being composed of two identical chromatids • Cytokinesis G. The cell leaves the non-divisional phase of the cycle and starts arranging the chromosomes for nuclear division H. As the chromosomes enter this phase, the DNA is at its most condensed/folded state, which allows for easy movement during mitosis I. The cell stops dividing at the end of this phase if Okazaki fragments are detected sf с 3. Order these stages of A mitosis for this model cell; label each with the appropriate phase name. B D ch . In which of the following phases of the cell cycle are the chromosomes in this configuration? Choose all that apply. a. G f. metaphase b. G anaphase

Ana Beophase of phase of the s-phase DNA is replicated Caka DNA Synthesis Go-phase The cell makes enzymes and other proteins which will soon be used in the M-phase, it finishes this phase twice the size it started at G1 phase. MultipWcation Mitosio > Unreplicated chromosomes becarne division (cell division) replicated, each being composed of following nuclear two identical chromatids. 6) The cell leaves the non-divisional mito sie cycle and starts Anophase I followed arranging the chromosomes for by Telophase nuclear division Prophase of HO As the chromosomes enter this phase, mitosis the DNA is at its most condensed/ folded state, which allows for easy movement dure during mitosis : Cytokinesis > I. The cell stops dividing at the (checks division) end of this phase if Okazaki during M-phase fragments are detected. → MITOSIS – prophase - Metaphase ( Nuclear Growth - Anaphane division and - Telo phase preparation → Growth and normal sphase formitosis. metabolic process Cytokineses - cytoplasm replication phare phase DNA division
