Please feel free to comment on student work at the bottom of the page. Students will be available to answer your questions. Students are tasked with exploring the stages of Mitosis and the changes that cells undergo during replication. Students represent each stage and examine changes in the number of chromosomes and the status of the chromosomes during each stage of mitosis. The project consists of a written component that guides students’ activities during the project and a physical component that can be a game or stop-motion animation.

## What Happens In Each Phase Of Mitosis

In my Cell Cycle project, I wrote a small game in Unity. It was more of an interactive demonstration of the cell cycle than an actual game, but this project was a challenge for me because I had almost no experience with C# or Unity, and I ended up learning a lot about object-oriented programming knowledge of my understanding of the cell cycle. The game simply goes through the stages of mitosis: It starts with interphase, where chromatin is located within the nucleolus. Next comes prophase, when nucleoli disappear and chromatin condenses into chromatids and replicates into chromosomes. Next comes anaphase, when all the chromosomes are aligned. In this stage, the player uses the arrow keys to move each chromosome to the highlighted center section. When they are satisfied with the position of their chromosomes, they can press the space bar. Next comes the end. The chromosomes divide again, and you individually control the two sides of the chromosome and move them to opposite centrosomes. The player presses the space bar to switch control to the new chromatids. Once completed, nucleoli form around each cluster of chromatids and the cell wall splits in the middle to form two cells. Mitosis is a biological process used to increase the number of cells containing identical genomic information. It is divided into four stages, namely

#### Mitosis Vs Meiosis

Mitosis consists of multiple processes that ultimately produce 2 identical new cells. The process of mitosis is shown below.

Interphase is the time between two cell divisions. During this stage, cells are in a quiescent state and are not dividing. Interval is the longest phase of the cycle, consisting of

After interphase, the cells prepare to undergo mitosis. During interphase, chromosomes are not visible.

During this stage, cells prepare for cell division. The nuclear membrane dissolves and the chromosomes are packed tightly together and move into the middle of the cell. At this stage, some microtubules are already attached to the chromosomes. When the nuclear membrane dissolves, we call it prophase or late prophase. Visible chromosomes will become visible.

### The Cell Cycle

During this stage, chromosomes attached to microtubules will meet in the metaphase plate. It is located in the middle of the cell between the two centromeres. The black dots in the picture below are closely packed chromosomes.

During anaphase, the chromatids will move toward the centromeres on either side of the cell. The purple spots in the image below are chromatids that are moving away from each other along the centromere (middle of the pink spot).

During this stage, two new nuclear membranes are formed to “capture” the chromatids. In addition, a new cell membrane is produced to separate the two new daughter cells through a stage called cytokinesis.

Growth and development of living organisms are possible due to mitosis. During the cell cycle, mistakes can be made. For example, microtubules can attach to the wrong parts of chromatids, causing unequal separation.

## Paper Plate Mitosis

These cells have control points where they can check if any errors have occurred. The cell can then take action, such as killing itself in a process called apoptosis. More information on cell cycle regulation can be found here. The cell cycle is an ordered series of events involving cell growth and cell division, producing two new daughter cells. During cell division, cells undergo a series of precisely timed and carefully regulated stages of growth, DNA replication, and division, resulting in two genetically identical cells. The cell cycle has two main phases: interphase and mitosis (Figure 6.3). During interphase, cells grow and replicate DNA. During mitosis, the replicated DNA and cytoplasmic contents separate and the cell divides.

Figure 6.3 A cell goes through an orderly sequence of stages. During interphase, G1 involves cell growth and protein synthesis, S phase involves DNA replication and centrosome duplication, and G2 involves further growth and protein synthesis. The mitotic phase immediately follows interphase. Mitosis is a nuclear division in which duplicate chromosomes are separated and distributed to daughter nuclei. Normally cells divide after mitosis, a process called cytokinesis, in which the cytoplasm divides and forms two daughter cells.

During interphase, cells undergo normal processes while also preparing for cell division. A number of internal and external conditions must be met for cells to move from interphase into mitosis. The three phases of interphase are called G

Stage, cells are quite active on a biochemical level. The cell is accumulating the building blocks of chromosomal DNA and related proteins and accumulating enough energy reserves to complete the task of replicating each chromosome in the cell’s nucleus.

## When Does Cytokinesis Occur In Mitosis?

Nuclear DNA maintains a semicondensed chromatin configuration throughout interphase. During S phase (synthesis phase), DNA replication results in the formation of two identical copies (sister chromatids) of each chromosome, firmly attached to the centromeric region. At this stage, each chromosome consists of two sister chromatids and is a replicating chromosome. Centrosomes replicate during S phase. The two centrosomes will give rise to the mitotic spindle, the device that coordinates chromosome movement during mitosis. The centrosome consists of a pair of rod-shaped centrioles at right angles to each other. Centrioles help organize cell division. Centrioles are not present in the centrosomes of many eukaryotic species, such as plants and most fungi.

During the second gap, the cell replenishes its energy stores and synthesizes proteins needed for chromosome operation. Some organelles are replicated and the cytoskeleton is dismantled to provide resources for the mitotic spindle. There may be additional cell growth during G

. The final preparations for the mitotic phase must be completed before the cell can enter the first phase of mitosis.

In order to make two daughter cells, the contents of the nucleus and cytoplasm must be separated. Mitosis is a multi-step process in which replicated chromosomes align, separate, and move to opposite poles of the cell before the cell divides into two new identical daughter cells. The first part of the mitotic stages, mitosis, consists of five stages that complete nuclear division. The second part of the mitosis phase, called cytokinesis, is the physical separation of cytoplasmic components into two daughter cells.

#### Solved Identify The Stage Of Mitosis For Each Of The Onion

Mitosis is divided into a series of stages—prophase, prophase, metaphase, anaphase, and telophase—leading to the division of the cell nucleus (Figure 6.4).

Mitosis is often accompanied by cytokinesis, as shown by transmission electron microscopy.

During prophase, or “phase one,” several events must occur to gain access to chromosomes in the cell’s nucleus. The nuclear membrane begins to rupture into vesicles, and the Golgi apparatus and endoplasmic reticulum fragment and disperse around the cell. The nucleolus disappears. Centrosomes begin to move to opposite poles of the cell. Microtubules that form the basis of the mitotic spindle extend between centrosomes, pushing the microtubule fibers farther apart as they lengthen. Sister chromatids begin to coil more tightly and become visible under a light microscope.

During prophase, many of the processes initiated in prophase continue and ultimately form the connections between chromosomes and the cytoskeleton. The remnants of the nuclear membrane disappear. Mitotic spindle development continues as more microtubules accumulate and extend the length of the pronuclear region. Chromosomes become more condensed and visually discrete. Each sister chromatid is attached to spindle microtubules at the centromere via protein complexes called kinetochores.

### Label The Pictures With The Correct Phase Of Mitosis:

During metaphase, all chromosomes align in a plane called the metaphase plate, or equatorial plane, halfway between the cell’s poles. Sister chromatids remain closely linked to each other. At this point, the chromosomes have reached maximum condensation.

In the later stage, sister
