D. uring Interphase DNA replicates which must occur before Mitosis can begin .. Extracting DNA from Your Cells . Today you will extract DNA from your cheek cells. This process is similar to what is done when any DNA-containing 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. . Syllabus reference:.

Cell Division Video Clip. Learning Goal: SWBAT describe and model the steps of mitosis. Scale of Understanding. Rate yourself on your level of understanding of mitosis-mark this on your sheet:. 4. Eukaryotes: organisms with a true nucleus and membrane bound organelles; usually multicellular. Animals, plants, fungi, protists (microorganisms). Eukaryotic cells replicate for growth and development . General Biology. Name. ________KEY_______________________. Reproduction. All Cells come from other cells (. Remember the cell theory?. ). Asexual – Organisms formed by only one parent; offspring are identical; fast; fine for environments that don’t change frequently since each organism is a clone. Metaphase. Anaphase. Telephase. Do now activity:. What would we find in the nucleus of a cell?. Why do cells need to divide. ?. What could go wrong when cells don’t’ divide properly?. GOOD PROGRESS:.
