Mitosis

WHO FIRST DISCOVERED MITOSIS? Mitosis was first discovered in the early 1880s by Walter Flemming. Walter Fleeming was a German biologist. He developed most of his study on cells and the chromosomes that are inside of cells. In 1878, the claimed that cell duplicate in the process called mitosis. Flemming died on August 4th, 1905. HOW DID MITOSIS GET IT NAME? "Mito-" which mean "thread" in Greek. The process of cell division are described as threads because during the process of…

amounts of caffeine and left Bulb A in water. We then recorded the number of roots and their average length on days two, three, and four. After that, we took and onion root form Bulbs A, B, C, and D, stained them, and looked for cells going through mitosis. Between the first and second day bulb A, B, C, and D all had growth in number of roots and average length. Also between day two and five bulb A, B, C, D also all had growth in number of roots and average length. Then bulbs B, C, and D were…

Chromatin, chromatids, and chromosomes have different transformations in terms of mitosis and meiosis. Chromatin in Meiosis and Mitosis are shown differently in Interphase. In Mitosis, the chromatin is made up of DNA and proteins. The DNA coils around the protein and that structure is called a nucleosome. Each chromatid in Mitosis is made up of many strings of the DNA and proteins (nucleosomes) to form a half X. The chromosome is made up of two of the chromatids (DNA and proteins-nucleosomes)…

revised. These analysts first stated the process by which cancer can occur based on multitudes of mitotic genes and proteins. One way oncogenic cells are able to form, based off of the original hypothesis, is through transcriptional malfunctions during mitosis. The tumor suppressors that are used in cellular division lose their function due to mutations, and the genes that have the ability to become cancerous due to over expression and/or mutations become more highly functioning. This gain and…

Interviewer: What is the first thing you do in the morning? Mitosis: I start my day with prophase. Interviewer: Why is that the first thing you do? Mitosis: Prophase is the first and longest phase in mitosis. During this time, the chromomsomes that I have start to become visable as paired chromatids. The nuclear envelope helps the chromsomes to come together and become paired.. Interviewer: Well whats you next phase that you have to go through? Mitosis: I go through interphase. Most of my day is…

The cell cycle is a cycle in which all cells do so they can replicate and take cover for dead cells. In order for them to do that they must go through all phases g1 phase g2 phase synthesis and then the mitosis phase. In the G1 phase the cell starts to grow preparing itself for mitosis but next it goes through G2 phase. The G2 phase is when the cell starts to rapidly grow and get protein which isn’t much…

bacterial growth and I was able to witness growth in its replication. Through the process of mitosis, I was able to view cellular reproduction. Lab Answers A. Bacterial growth observation. The population doubling time is estimated to be 20 minute. B. Cellular reproduction : The three types of cell separation are : The binary fission, Mitosis, and Miosis. Binary fusion are prokaryotes cells and mitosis and miosis eukaryotes. All of the cells reproduce. Prokaryotic cells when they are…

and uncontrolled cell growth can commence. The cell cycle has two main phases, Interphase and Mitosis the final stage is very important, but it is also small, cytokinesis stage is the final stage of the cell cycle. Interphase consists of three stages of the cell cycle, G1, S,…

Observation of mitosis in Onion root tips Answer the following question to its full explanation: 1. What is Cytokinesis? Compare and contrast cytokinesis between plant and animal cells. Cytokinesis is the last step in cell division, where the cytoplasm divide and the two daughter cells appear. In Animals, the cytokinesis processes occurs through cleavage. Firstly, in the old metaphase plate position, a cleavage furrow is formed. On each sides of the furrow, a contractile ring formed of actin…

known as G1 phase, S phase, G2 phase, & M phase. The G1 phase is where the cell is assigned to enter the process for chromosome duplication. DNA replication occurs in the S phase. The third phase, G2 phase, the process of mitosis triggering the alignment of the mitotic spindles. Mitosis and cytokinesis are two important functions that occur throughout the M phase. The three stages…
