Question;Cancer and;Genetics;Unit II Assessment;Introduction;In order for organisms to grow, repair, maintain, and reproduce, cells;undergo cell division. Sometimes, cells uncontrollably divide, resulting in;cancer. In the first part of the Cancer and Cell Division Lab, you will learn;about normal cell division and will compare it to cell division that occurs in;cancer cells. You will then visit a website to find out more information about;cancer. You will learn why it occurs, why it kills, and new treatments that are;being tested and used to treat cancer.;Objectives;1.;Explain the process of cancer;the effects on the human body, the various types, and the risk factors;involved.;2.;Explain various treatments for;cancer.;3.;Explain the various stages of;mitosis.;Materials;No extra materials will be required to complete this lab other;than internet service.;Directions;?;Go to the following website:http://www.mhhe.com/biosci/genbio/virtual_labs/BL_23/BL_23.html;?;Follow the steps under the;Procedure section.;?;Type all answers directly on the data sheet.;?;Select Save As, and save this document using;your last name and student ID as the file name.;?;Upload the data sheet as a.doc,.docx, or;rtf file when you are finished.;While viewing the video, answer the following questions. Each;question is worth 2 points.Total: 4;points;1.;In which stage of cell division;is the DNA copied?;2.;During which stage of mitosis do the chromosomes;line up in the middle?;After;viewing the video, click on the Information tab in the bottom right corner.;Answer the following questions. Each question is worth 2 points.Total: 6 points;1.;In which of the cancer types;listed, are males not at risk of developing?;2.;Cigarette smoke is a major risk;factor for which type of cancer listed?;3.;The risk for which type of cancer increases;after the age of 55?;Continue following the directions under the Procedure Section;and complete the following table. The table isworth 17;points.;Interphase;Prophase;Metaphase;Anaphase;Telophase;% of Cells Dividing;% of Cells at rest;Normal Lungs;Cancerous Lungs;0;Normal Stomach;0;Cancerous Stomach;Normal Ovary;Cancerous Ovary;Continue following the directions under the Procedures section;and answer the following questions. Each question is worth 3 points.Total: 9 points;1.;Based on your data and;observations, what are some of the Differences between normal cells and cancer;cells?;2.;Which type of cancer shows the;most aggressive growth? Explain your answer.;3.;When studying cell division in;tissue samples, scientists often calculate a mitotic index, which is the ratio;of dividing cells to the total number of cells in the sample. Scientists often;calculate the mitotic index to compare the growth rates of different types of;tissue. Which type of tissue would have a higher mitotic index, normal tissue;or cancerous tissue? Explain.;Go to:http://www.cancer.org/;Click on: Learn About Cancer. View each section contained in the;menu under Learn About Cancer Topics and answer the following questions. Each;question is worth 2 points.Total: 14;points;1.;How many people in the US get;cancer each year?;2.;What causes cancer?;3.;Since there are many different;types of cancer, how is cancer named?;4.;List 2 signs or symptoms of;breast cancer.;5.;Can males development breast;cancer?;6.;What is the most common type of;cancer?;7.;List two ways you could get;involved and help fight against cancer.
