attached image is an image of the cells you would have been looking at under the microscope Count at least 50 cells. When done, there should be at least 50 marks on the table (one mark for each cell). You may need to count more than 50 to find at least one of every phase. Calculate the proportions, and estimate the amount of time spent in each phase and subphase. The table will lead you through how this works. Take the number of cells in a particular phase, divided by the total number of cells examined (i.e., 50—or more), then multiply by 24 (the number of hours an average onion root tip cell takes to complete the entire cycle. This should give the hours a cell spends in each phase. Again, this assumes, that the entire cell cycle for onion root cells is 24 hours. This time can vary in different organisms. FILL-IN this table with the results of your count of 50 cells Phase/Subphase # of cells Calculation (fraction of cells x total hours of the cell cycle) # hours spent…
In order to investigate the cell cycle in HEK293 cells in culture, I ran a flow cytometry experiment. I labeled their nuclei with DAPI to analyze DNA content. In these flow cytometry plots below, label the two main phases of the cell cycle that you can see. Briefly, explain your answer.
A cell stops proliferating when treated with a chemical analog to fucoxanthin. When these cells are analyzed and compared to untreated cells according to the amount of DNA they contain using flow cytometry, the graphs in the figure below are obtained. Which of the following answers would NOT cause this result?
State 3 important results of meiosis. For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac). TTT Arial ✓ 3 (12pt) ✓ T-E One parent cell undergoes mitosis, which results in the division of two identical daughter cells. Definition of primal Mitosis is the mechanism of reproduction in unicellular eukaryotes. For eukaryotes with many cells: Mitosis boosts cell production and promotes bodily growth and development.Damaged tissues or organs can be repaired by mitosis.Mitosis is a kind of reproduction for vegetative organisms that results in offspring with the same genotype as the parent.
z e 50 μm Figure 3. Grasshopper testis with differential staining and viewed under a microscope. Encircle the cell and label the specific stage in the meiosis it displays. Identify as many as you can witha minimum of two cells representing different stages. Make sure to specify whether the stage belongs to meiosis I or II. If you identify a cell at prophase I, then specify the substage.
The following data indicates the percentage of time an average animal cell spends in each part of the cell cycle if it replicates every 24 hours. Stage of Interphase G1 S-phase G2 Average Percentage of Time Spent 50 % 23% 19% Stage of Mitosis Prophase Metaphase Anaphase Telophase Average Percentage of Time Spent Procedure 1-2: Identifying Str 4% 0.8 % 0.18% 3% 1. Redraw the cell cycle in a pie chart representing the amount of time spent in the different parts of the cell cycle. 2. The cells in our body do not replicate every 24 hours. What parts of the cell cycle do you think are extended when a cell's cycle is longer? Why? Why do the other parts of the cycle not get longer? 3. Compare when DNA is being replicated during the cell cycle to the amount of time the cell is performing transcription to eventually make proteins. How many times in a cell's reproductive cycle does the duplication of DNA occur vs the amount of time the cell is transcribing the DNA. Why does this make sense with…
Which of the following options correctly describes the functions of both cilia and flagella? Excretion Protection Locomotion Body’s defense BENTEN: During meiosis I, pairs of homologous chromosomes align randomly along the metaphase plate before being separated. This process helps generate genetic variation in the offspring of sexual reproduction. Which of the following best explains how the random alignment of homologous chromosomes during meiosis helps generate varied offspring? Random alignment increases the likelihood of crossing over between non-sister chromatids. Random alignment results in the formation of gametes that contain different numbers of chromosomes. Random alignment increases the number of possible chromosome combinations in the gametes. Random alignment results in the formation of some diploid and some haploid gametes.
Draw or explain in a simple manner what needs to be done in each step of modeling mitosis. Steps/ Procedure: 1. Tie the ends of a 10-ft (3-m) piece of string together and form a circle on the table. This represents the cell membrane of a parent cell. 2. Make a smaller circle from a 5-ft (1.5-m) piece of string to create a nuclear membrane, and place it inside the cell membrane. 3. Place 1 sock of each pair into its mate and jumble the socks inside the nuclear membrane. 4. During interphase, the cell prepares for nuclear division and DNA replicates. To simulate replication, remove a mate from each pair of socks. Match sister chromatids and connect them at their centromere by tying the matching pairs together at their centers with a small piece of string. Place them back into the nuclear membrane, jumbling them up. 5. Mitotic division now begins with prophase. During this phase, DNA condenses into chromosomes made up of 2 identical sister chromatids, and the nuclear membrane breaks…
