What 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. Attachment of microtubles to kinetochores

What is the function of the replication enzymes during S phase of the cell cycle?1. Holding the sister chromatids together until they are separated during mitosis2. Keeping the DNA tightly coiled3.Copying the DNA in the chromosomes4. Pushing the sister chromatids to opposite poles of the cell

Answer choices: 1) a cell with two complete sets of chromosomes  2) a chromosome pair, one maternal and one paternal 3) the events that occur from the time a cell forms until the time it divides 4) time of cell growth 5) cell division that maintains chromosome number 6) a reproductive mode by which offspring are produced by one parent only 7) an exact copy of a chromosome

1. Mitosis: a. Are the chromosomes at each pole during telophase identical to chromosomes in the original cell (prior to S phase of cell cycle)? b. Are the new daughter cells genetically identical to the original cell? c. Does crossing over occur in mitosis? Explain.
