PPT-Extraction of DNA from Human Cheek Cells

Extracting DNA from Your Cells Today you will extract DNA from your cheek cells This process is similar to what is done when any DNAcontaining tissue is found at a crime scene Cells from the lining of your mouth come loose easily so you will be able to collect cells containing your DNA by swishing a liquid around in your mouth The cells from the lining of your mouth also come off whenever you chew food . Purpose. To view DNA from human epithelial cells. Background. Where is the DNA located? . Cheek Cells. Cells from the lining of your mouth come lose easily. We will be able to collect cells containing your DNA by swishing a liquid around in your mouth. . Biology . ONION CELLS . Cheek Cells. Cheek Cells. 1. 00x. cell membrane. cytoplasm. nucleus. Cheek Cells (stained). 400x. cell membrane. cytoplasm. nucleus. Onion . Cells (stained). 1. 00x. cell wall. cytoplasm. nucleus. Onion Cells (stained). 400x. Comparing and contrasting onion and cheek cells. Inquiry Question. How do you think an onion cell would be different from a cheek cell? . Describe shape, size, and organelle differences that you expect to observe.. Carbon based molecules are called Organic Compounds. Life’s molecular diversity is based on the properties of Carbon. Carbon is unparalleled in its ability to form large diverse molecules. Carbon has the ability to form covalent bonds (sharing of electrons). Activity Overview. Extract DNA from strawberries using simple household chemicals. DNA EXTRACTION USING STRAWBERRIES. 2. Questions: . what does DNA stand for?. what is DNA?. 3. You mean I can see it? HOW?. And other veggie cells. Fruits . and . vegetables are made of cells. Evidence that proves this is . that. we took a . vegetable. and/or fruit and looked at it under a microscope. While looking under the microscope we had to use either . Goals and Objectives:. S. tudents will understand that . cells contain . DNA. . . DNA . is a physical structure that can be seen with an unaided eye. Students will prepare a solution containing . strawberry . However. , the behavior of transplanted hIPSC and hESC in immunocompetent mice is less well . understood.. Previous work in the Knoepfler Lab and Martinez-Cerdeno Lab revealed strong engraftment of both hESC and hIPSC by immunohistochemistry . Parts of the Human Cheek Cell at 40X Magnification. Can you name these parts of the Human Cheek Cell?. CELL CYCLE. D. uring Interphase DNA replicates which must occur before Mitosis can begin .. Centrioles. # 1 Cheek Cells. These cells were gently scraped from the inner surface of a person’s cheek, and placed on a microscope slide. The cheek lining cells are thin and flat. They fit together like tiles on a floor, except that they overlap slightly. Because they are thin and flat and several layers thick these cells make the lining of the cheek smooth, flexible, and strong. The large dark spot in the center of each cell is the nucleus. .
