Exercise 13 MITOSIS: REPLICATION OF EUKARYOTIC CELLS ANSWERS TO QUESTIONS 1. a. Mitosis and cytokinesis are often referred to collectively as "cellular division." Why are they more accurately called cellular replication? The result of mitosis is production of two cells (replicates) identical to the parent cell. The genetic material is replicated rather than divided. b. Does the cell cycle have a beginning and an end? The organization of our study of cellular events indicates a beginning and

only during the S phase. A typical animal cell might divide once every 24 hours. Of this time‚ the M phase would last less than an hour‚ while the S phase might take 10–12 hours‚ or half the cycle. The rest of the time would be divided between the G1 and G2 phases. The G1 phase varies most in length from cell to cell. The mitotic (M) phase consists of mitosis and cytokinesis. Mitosis is usually broken into five subphases: prophase‚ prometaphase‚ metaphase‚ anaphase‚ and telophase. During prophase

What will happen if ancient people got computer? One day‚ in 800 B.C.‚ the people were farming as normal day. Suddenly‚ the person who was working on the left side found something on the ground. It was white box with black surface‚ which was quite shiny without getting sunlight. Everyone thought that is a treasure of god and tried to dig out as soon as possible. When they revealed about half of object from ground‚ they noticed another thing - the grey‚ round and handy thing that was connected

Mitosis and meiosis are both important biological processes that happen within eukaryotic cells. These two processes are slightly different from one another‚ but have a lot of similarities. Before each of these processes can be performed‚ the cell first has to go through interphase. Interphase is considered the primer for mitosis or meiosis and consists of: G1‚ S‚ and G2 phases. These phases prepare the cell for either mitosis or meiosis by causing the cell to grow‚ copy the DNA‚ and copy the cell’s

Anti Racism- MUST BE STOPPED What is anti-racism? It means treating everyone fairly‚ not making racist jokes‚ respecting people and being friendly to each other‚ regardless of where they come from or what they look like. We were born to trust and accept each other. We were not born with particular attitudes or prejudice. Today we often read and hear people criticise one particular race‚ their religion and their behaviour. Sometimes we are encouraged to take on the mistaken belief that there

Mitosis is the process in which a cell breaks apart its chromosome to eventually produce two identical daughter cells. The cell spends 10% of its time in mitosis. The cell goes through four stages in order to complete this task. The stages are Prophase‚ Metaphase‚ Anaphase and Telophase. Mitosis only occurs in eukaryotic cells and the process is different for different species. Mitosis is fast and very complex. The first phase is Prophase. In prophase‚ the chromosomes the chromosomes start to

Mitosis v. Meiosis Biology is the study of life and the processes that a life form undergoes. Two very important biological processes in the field of biology are mitosis and meiosis. These two biological processes comprise the majority of what is studied in every cell unit within biology class. Many students have a difficult time understanding the similarities and differences between the two. Students also struggle to understand the phases of each cell division and the reason they occur. Mitosis

It is important that cells go through mitosis because it makes each new cell contain the same gentic information. If meiosis did not occur the reproduction would cease to exist. Mitosis is the process of chromosomes dividing. There are four steps that it goes through. Between cell division the cells are in interphase. During this there is cell growth and the genetic material such as DNA is contained in the chromosomes‚ duplicated so that when the cell divides each new cell has a full version of
