  • Transcript of "Mitosis lesson 1 revised"

    1. 1.    All living things are made of cells. Cells are the basic unit of life. Cells come from other cells. Schwann – animal cells 1839 Schleiden – plant cells 1839 Virchow – cell come from pre-existing cells 1855
    2. 2.     Cells contain genetic material in the nucleus of the cell called DNA. DNA – Deoxyribonucleic Acid DNA is found in the chromosomes (structures found in the nucleus of the cell) DNA carries the “genetic code” for that organism
    3. 3. DNA is sometimes called "the blueprint of life" because it contains the code, or instructions for building and organism and ensuring that organism functions correctly. Just like a builder uses a blueprint to build a house, DNA is used as the blueprint, or plans, for the entire organism.
    4. 4.    It is the chemical component of chromosomes, which are located in the nucleus of every cell. Stretches of DNA (or stretches of chromosomes) code for genes. Gene - a segment of DNA that codes for a protein, which in turn codes for a trait (skin tone, eye color..etc), a gene is a stretch of DNA. The structure of DNA was established by James Watson and Francis Crick.
    5. 5.    Where do cells come from? All organisms begin as one cell. How do cells reproduce?
    6. 6.   In unicellular (single celled) organisms, the cell divides to make new versions of itself. In multicellular organisms, the cells divide and then specialize to become different structures such as heart, brain, lungs, etc. Every day, your skin cells die and replace themselves by reproducing new ones. They do this by division.
    7. 7.  This process of division is called Mitosis – is a process in which a cell divides resulting in two identical cells, each containing the same number of chromosomes and genetic content.
    8. 8.    Chromosomes – DNA – Centrioles
