ACTIVITY A. Identification of the Interphase and the Stages of Mitosis: Identify the different stages of the cell cycle described as follows: 1. A large spherical nucleus, with the nuclear membrane intact, grainlike chromosomes and one to two nucleoli. This is the stage of __________. 2. A large, spherical nucleus with a nucleolus and nuclear membrane intact and with thickened, more distinctly ribbonlike chromosomes. The chromosomes may look like a dish of spaghetti. This is the stage of __________. 3. A cell in which the chromosomes appear as a loose knot in the center of the cell. The nuclear membrane, if still present, is indistinct. The nucleolus may start to fade. This is the stage of __________. 4. A cell in which the chromosomes are aligned in the equatorial plane of the cell. This is the stage of __________. 5. A cell in which the chromatids are moving to opposite poles of the cell. This is the stage of __________. 6. A cell in which the chromatids, though fairly distinct, are close to the opposite poles of the cell. A cell plate may be forming at the middle of the cell. This is the stage of __________. 7. Look for two cells that appear to have finished dividing recently. These are the daughter cells and the stage seen is the stage of __________.

Topic: Cell Cycle (Interphase, Mitosis, and Cytokinesis) The cell cycle describes the process that occurs throughout the body where one cell divides into two identical cells for repair, growth, and development. It is divided into two main parts: Interphase and the mitotic phase. Interphase (G1, S, and G2) is the longest part of the cell cycle. During G1 and G2 of Interphase, the cell is carrying out normal functions as well as growing, accumulating energy, and making proteins. However, during the S phase, DNA replication occurs. The mitotic phase includes mitosis and cytokinesis (See Chapter 6.2). Explain why it is essential that the genome of a cell be copied before the cell divides into two. Mitosis (See Figure 6.4) and note when (prophase, metaphase, anaphase, or telophase) each of the following occurs: - Spindle apparatus assembles - Spindle apparatus disassembles - Chromosomes condense - Chromosomes decondense - Nuclear envelope fragments - Nuclear envelope reforms - Chromosomes line up at the mid-point of the cell - Sister chromatids are pulled to opposite ends of the cell Cytokinesis is not a part of mitosis, even though it may begin before telophase (part of mitosis) is complete. (See Figure 6.4) What happens to the cell in cytokinesis? Answer yes or no to the following statements about the cells produced in the cycle: - The two cells produced are identical to each other. - The two cells produced are identical to the original cell before division. The two cells produced typically function in growth, development, and repair. (See the Introduction to Chapter 6) Lack of regulation in the cell cycle can lead to tumors.

Interphase, Prometaphase, Metaphase, Anaphase, Telophase, Cytokinesis. Chromosomes align on an imaginary line equidistant from each pole. Nuclear division that distributes chromosomes equally to daughter cells. Chromatin fibers become more condensed to form discrete chromosomes. Nucleus is well defined and bounded by the nuclear envelope. Includes G1, S, and G2 phases. Centromeres separate and the sister chromatids are now individual chromosomes. Chromosomes move toward opposite poles of the cell. First period of cell growth after mitosis is completed. Cell continues to grow but is now completing preparation for mitosis. Chromosomes become less distinct and chromatin forms, each chromosome becomes less tightly coiled. Mitotic spindle begins to form by extending from the two centrosomes. Phase during which DNA is synthesized. Nuclear envelope fragments and spindle fibers attach to kinetochores of chromatids. Division of the cytoplasm.

00:01 Hi students, in this question we are asked the names of the stages of cell cycle activity.
00:15 So first stage that has asked is about the large spherical nucleus with the nuclear membrane intact.
00:23 So this stage is prophase.
00:26 This stage is prophase.
00:30 Then second, about the large spherical nucleus with the nucleolus and the nuclear membrane intact.
00:36 And with a thickened and more distinctly ribbon -like chromosomes, then the second stage is the meta phase stage.
00:45 Second is the meta phase stage...
