- During the cell cycle, in which sub-phase(s) of interphase does the cell replicate its chromosomes? a. G1 phase b.S phase Oc. G2 phase Od. G1 and G2 phases Oe. G1, S, and G2 phases е. QUESTION 48 With regard to the process of mitosis, which of the following pairs is NOT matched correctly? a. Interphase - the cell grows, chromosomes replicate, and proteins are produced to prepare the cell to divide b. Prophase - chromosomes condense, and the nuclear membrane dissociates/breaks down c. Metaphase - chromosomes move toward opposite poles (or sides) of the cell d. Anaphase - sister chromatids separate e. Telophase - two distinct nuclei are formed; this is the stage immediately before cytokinesisWhat celluar events/processes are associated with G1,S,G2,and M phases of the cell cycle? With the phases of mitosis? Some example: A. DNA replication B. Beginning of mitosis C. Normal cell growth and function D. Breaksdown of nuclear membrane E.Separation of sister chromatids F.Alignment of chromosomes on the equator of the cell H.Triggering the compaction and condensation of chromosomes I.

None of the other choices is valid O b. To provide dissolved dissolved 02 O c. To provide dissolved dissolved CO2 O d. To provide dissolved waterWhich of the following is least likely to result in the formation of a cancerous cell?

A dysfunction in a cell cycle checkpoint prevents a cell from entering the S phase. A dysfunction causes the inability to produce cancer-suppressing proteins.

Metaphase B. Condensed and highly colled chromosomes move to a central zone. Prophase C. During this phase, chromatin condenses into two Identical coples of each chromosome. V Anaphase D. Chromosomes begin to pull toward opposite ends. Cytokinesis E. The nuclear envelopes will form around each nucleus and the nucleol will reappear.
