Recommended: A descriptive summary of mitosis

Prometaphase and reverse prophase are two stages in the process of mitotic cell division. Prometaphase is the middle step between prophase and metaphase during mitosis. During prometaphase, the nuclear envelope (the sack in which the nucleus lies in) is broken down, two kinetochores form at each centromere, and microtubules attach to the chromosomes. Polar microtubules push against each other and that forces each centromere to go to opposite ends of the cell, preparing it for metaphase. Reverse prophase is also more commonly known as telophase. Telophase is the last step of mitosis, during which the chromosomes move to opposite ends of the cell and the nuclear envelope begins to reform around the daughter sets of chromosomes. After which, cytokinesis will occur and two identical daughter cells will be formed. …show more content…

Mitosis has 4 identifiable stages: prophase, metaphase, anaphase, and telophase/cytokinesis. Prophase is the first stage of mitotic cellular division in which the centrioles separate and move to opposite ends of the nucleus. Proceeding is prometaphase, whereas described above, is when microtubules attach to the chromosomes to prepare them for the next phase: Metaphase. Metaphase is the third step of mitosis where the chromosomes align along the metaphase plate to prepare for division. To form the two daughter cells, anaphase, the next stage, separates the chromosomes and they move to opposite ends of the cell. Lastly, telophase/cytokinesis occurs in which the nuclear envelope reforms, the cellular membrane (and cell wall in plant cells) is cleaved and rebuilt. From that process two identical daughter cells are

    10.4) In animal cells cytokinesis involves the formation of a cleavage furrow which pinches the cell in two. While in plants cells cytokinesis involves the division of cytoplasm by late telophase, so the daughter cells appear shortly after the end of mitosis.

  • Left or Right?

    1160 Words  | 3 Pages

    According to J.K Rowling, “It is our choices that show who we truly are, far more than our abilities.” This conclusion postulates that it does not matter whether a person is fragile or robust, brilliant or dull, gifted or challenged, it is the choices that they make in life that crystallize who they are as people. Yet, can these words be ripped from their simple format and be plastered to the pillars of life themselves? For example, does the child protégé always have the will power to use their knowledge and select the right path? Or does the godlike athlete always think twice before taking a third steroid pill that week? In other words, this statement truly holds the glittering gold of truth and is often exhibited throughout society, and frequently through history as well. Two pieces of literature that clearly demonstrate this idea of a person’s personal building blocks being their decisions are the novel, Of Mice and Men, by John Steinbeck and the Epic Poem, The Odyssey, by Homer. These texts both support this observation by requiring the protagonist to formulate great decisions that define them as people and what will be in store for them later in life.

    I believe Frankenstein is a villain in this book. I believe he promotes the idea of evil which is symbolised through creating the creature. He is described as “a creature causing havoc”. The creature is an unwanted person. He has no belonging in this world. He was created, and because of this, he is an outcast because of Victor Frankenstein. The creature is the victim. He is lonely and rejected. Frankenstein is the cause of this. I believe it is wrong to play god. No man should try and create human beings. He has created a being that is driven to the extremes of loneliness in life. This is destroying innocent lives.

  • PRP injections

    In the past decade, the demand of performance from elite athletes has risen drastically. This demand brought about more injuries, in turn increasing the demand for quicker recovery times from surgery or from an acute injury in these top athletes. Doctors have discovered what they believe to be a helpful solution to the problem, Platelet-Rich Plasma Injections (PRP). These injections are to be administered directly into an athlete’s injured tendon. PRP is a process that essentially separates your blood through bone marrow, leaving part of it extremely strong. However, the reasons for the strength are due to it coming from the patient’s stem cells, bringing non positive attention to this new age treatment. Because this stronger, platelet-rich plasma contains your own IGF-1, which is a growth factor that helps you heal. The platelet-rich portion of the blood can be injected back into the body directly at the site of the injury, with the intent of a faster recovery time. What is to be determined is if the PRP injections work well enough to become a standard treatment method and if this treatment is morally acceptable.

  • Comparing Metamorphosis And Persepolis

    The clever use plot to project a story which criticizes society is what we can see in Franz Kafka’s Metamorphosis and Marjane Satrapi’s Persepolis. In both these novels the characters are integral part of a social commentary on specific society they are living in. While Gregor Samsa (Metamorphosis) struggles to cope with his family but also tries to find out his own individuality comments on the capitalistic society where working and earning money is the norm, Marji (Persepolis) is going through a phase of rebellion in a country where the social norms are made too dense in name of religion. Both of these novel give the readers a plot based on commentary on the rules that the society has imposed and which forces the character to come out of their normal to rebel against the society and find their own individuality.

  • Metamorphosis and Heart of Darkness

    Although both Joseph Conrad and Franz Kafka distance their protagonists from conventional society to represent the shallowness of mankind, Kafka does so through internal changes whereas Conrad creates external changes. In Heart of Darkness, Conrad removes Marlow from accepted society to show how challenges man suffers through to survive on their own with the superficiality surrounding them. Kafka exiles Gregor in Metamorphosis to demonstrate the ignorance people have for others physically and mentally different from themselves through Gregor’s transformation and the isolation he endures. Both authors transition their main character into a new environment, and combine the new environments with different behaviors to live with.

  • Cell Division Essay

    The differences between the phases of mitosis and meiosis are that in mitosis, it has 1 cell division, duplicates the DNA, occurs in somatic cells, and no crossing over happens. In meiosis, it has 2 cell divisions, reduces the DNA, occurs in gametes or sperm and egg cells, while crossing over happens. They are both similar in which they both create daughter cells, headed by at least one round of DNA replication, and have similar stages for cell division.

    Proxemics is the study of the distance people leave between themselves and others within various situations and in various cultures. In everyday life people distance themselves although it is a subconscious action. Proxemics was observed between the employees working in the radiology department of a local hospital. The observation took place throughout the whole department which included exam and procedure rooms as well as staff lounges and waiting rooms. The department is relatively small and does not allocate a large amount of space in between work environments. Gender, age, education, family background, and level of association are factors that determined the proxemics in the radiology department.

    All cells are the product of multiple rounds of cell growth and division, new cells are formed from existing cells, as has been the processes since the beginning of life on Earth. The reproduction of new cells is a very organized sequence of events called the cell cycle. This cycle is the essential mechanism by which all living cells reproduce whether unicellalur or mutlicelluar the basic mechanism is universal. However, variations in the details do occur from organism to organism and the cycle can start at different times in the organism’s life. The Eukaryotic cell cycle usually consist of four phases.
