Question
Indicate which phase of the cell cycle is described in each of the following statements: A. anaphase B. metaphase C. prophase D. telophase E. none of these ___ chromatin coils/condenses to form deeply staining bodies ___ nuclear membrane & nucleoli reappear ___ centromeres break & chromosomes begin poleward migration ___ chromosomes cease poleward migration ___ chromosomes align at equator of spindle ___ nucleoli & nuclear membrane disappear ___ spindle forms through the migration of the centrioles ___ DNA replication occurs ___ chromosomes are duplex structures (2) ___ chromosomes attach to the spindle fibers ___ cytokinesis usually begins ___ nuclear membrane is absent during the entire phase (2) ___ period when the cell is NOT in the M phase ___ chromosomes are V-shapedExplanation / Answer
Anaphase - centromeres break and chromosomes start poleward migration
- DNA replication occurs
- nuclear membrane is absent during the entire phase
- chromosomes are v shaped
metaphase - centromeres align at equator of spindle
- nucleoli and nuclear membrane disappear
prophase - chromatins condense to form deeply staining bodies
telophase - nuclear membrane and nucleoli reappear
- cytokinesis usually begins
none of the above - period when cell is not in m-phase
