Select all the features of mitosis that are true.

Which of the following is NOT a checkpoint that controls the progression of cell cycle? The metaphase checkpoint determines if all chromosomes are attached to the spindle apparatus Cytokinesis involves the formation of cleavage furrow to separate the cells The G2 checkpoint checks for DNA damage and determines if all of the DNA is replicated Cyclins and cyclin dependent kinases are protejns that are responsible for advancing a cell through the phases of the cell cycle

Which of the following statments about the cell cycles is correct? When the S phase of the cell cycle is finished, a cell has twice as many chromatids as the number of chromosomes in the G1 phase In actively dividing cells, the S and G2 phases are collectively known as interphase The phases of the cell cycle are G1, S, and M phases The cell cycle is a sequence of replications and divisions that produces new cells

Match the following to the descriptions provided.

What are the stages of mitosis (interphase=I, prophase=P, metaphase=M, anaphase=A, telophase=T) during which each of the following events occur. Chromosomes are at oppoiste poles of the cell, cytokinesis is almost completed. Chromosomes (chromatids) first become visible as long thin strands. DNA (chromosomes) replicate occurs

Put the following phases of the cell cycle and mitosis in the correct order. Prometaphase Interphase - S phase Telophase Prophase Anaphase Interphase - G1 Metaphase Interphase - G2

Cell W has half as much DNA as cells X, Y, & Z. Which phase of the cell cycle is cell W in? G1 G2 Metaphase Prophase

The cells bellow are in the process and stages as indicated. Each cell has a 2n # of 6. In the cells below show all of the chromosomes and their proper location and draw and label the metaphase plate, kinetochore, spindle, centrosomes, homologous chromosomes, microtubules, DNA, sister chromatids, centromere MITOSIS (Metaphase) Total number of chromosomes Total number of homologous pairs of chromosomes MEIOSIS (Metaphase I)

Mitosis Meiosis Definition Prophase Metaphase Anaphase Telophase Prophase I Metaphase I Anaphase I Telophase I Prophase II Metaphase II Anaphase II Telophase II Steps of each phase Number of cell divisions Number of cells produced *How many chromosomes per 46 daughter cell? * Mitosis starts with 46 chromosomes in each parent cell, and then ends with 46 chromosomes in each daughter cell. Cells divide onl once in Mitosis, but they divide twice during Meiosis, so we should end with half as many chromosomes in Meiosis vs Mitosis.

Use the following information to answer the next question. A diet rich in lycopene, a nutrient found in tomatoes, can reduce the risk of cancer by preventing genetic damage and abnormal cell growth. Lycopene has been shown to reduce the size of tumors and slow the spread of the cancer to somatic cells. Lycopene slows the spread of cancerous growth by decreasing the rate of Select one: mitosis, which produces diploid cells meiosis, which produces diploid cells mitosis, which produces haploid cells meiosis, which produces haploid cells O O

The following phrases refer to the eukaryotic cell cycle. Select the single BEST choice for each phrase. Period when DNA is duplicated Last part of interphase in the parent cell Event that divides a cytoplasmic mass Period of cell growth before DNA duplication Period after DNA is duplicated Nuclear division that maintains the chromosome number Period when interphase begins in a cell Period commonly followed by cytokinesis - Period in which metaphase occurs Period prior to mitosis a. G2 b. Mitosis c. S d. G1 e. Cytokinesis

Match the phases of meiosis with the correct description Metaphase I [ Choose ] [Choose ] Sister chromatids line up along the center of the cell. Cytokinesis produces four unique daughter cells, spindle dissolve, and the nuclear envelope reappears. Spindle fibers pull homologous pairs of chromosomes apart. Nuclear envelopes of daughter cells dissolve, and chromosomes condense. Spindle fibers pull sister chromatids apart. Homologous pairs of chromosomes line up at the center of the cell in tetrads. Cytokinesis produces two daughter cells, spindle dissolves, and nuclear envelope reappears. Nuclear envelope dissolves, DNA condenses and crossing over occurs.
