Mitosis

The life of a cell, consisting of a growth stage (interphase) and a division stage (mitosis), is referred to as the: nucleus cycle cell cycle chromosome cycle phase cycle The cell spends most of its life in this phase: interphase cytokinesis metaphase prophase Which phase do the sister chromatids separate? prophase anaphase telophase cytokinesis How many daughter cells are there after mitosis occurs? 2 8 4 16 True or False: The daughter cells are identical to one another. True False If a cell begins with 12 chromosomes, how many chromosomes will the new daughter cell have? 6 24 12 3 Fibers that attach to sister chromatids to pull them apart during mitosis are referred to as: centromeres chromatin cytoplasm strands spindles The structure that joins two sister chromatids in a duplicated chromosome is referred to as the: spindles centromere chromatin centrioles Why is it important that a cell's DNA is replicated before mitosis occurs? So that each new daughter cell will contain all of the DNA So that the cell increases in size So that the DNA stays in the nucleus So that the surface area to volume ratio is small Fill in the diagram below. Make sure to COPY AND PASTE. spindle fibers sister chromatids chromatin centrioles spindle fibers sister chromatids chromatin centrioles Label the different phases on the diagram below. Make sure to COPY AND PASTE. telophase metaphase interphase anaphase prophase interphase prophase metaphase anaphase telophase Match the characteristic with the phase in which it occurs. The cell replicates its DNA and grows in size before division. Interphase First phase of Mitosis where chromatin condenses into visible chromosomes and the nuclear envelope begins to break down Prophase Phase of Mitosis where the chromosome line up at the equator (middle) of the cell Metaphase Phase of Mitosis where the sister chromatids are pulled apart by spindle fibers to opposite poles Anaphase Phase of Mitosis where chromosomes arrive at the poles, chromosomes de-condense into chromatin, and the nuclear envelope re-forms Telophase The cytoplasm splits and 2 identical daughter cells are formed Cytokinesis
