MITOSIS
Mitosis (Asexual Reproduction)
We need to make new millions of new cells for growth, cell replacement (when existing cells die), and for repair (such as healing a cut). How do we do this? Mitosis! Mitosis is the process during which one (parent) cell splits into two identical (daughter) cells. We learned earlier in the year that for asexual reproduction, there is only one parent. The parent can make babies that are identical to them, or clones. How do they do it? Mitosis, of course! Bacteria can also clone themselves using binary fission. Binary fission uses a different process than mitosis but results in two identical cells. We will learn about the main parts of the cell cycle. These include: #1. Interphase #2. Mitosis and #3 Cytokinesis. We will also learn about the phases of mitosis or PMAT (prophase, metaphase, anaphase, and telophase). Welcome to the world of CELL DIVISION!
We will also discuss stem cells and cell differentiation. Each body cell (somatic cell) in your body contain the exact same # of chromosomes (46!) with the same DNA, yet we have about 220 different kinds of cells that look very different and perform very different jobs. How does this occur? When a sperm and cell join, undifferentiated cells (stem cells) divide rapidly. Eventually certain genes within the DNA get turned off (like a light switch getting turned off). It is the different combinations of turned off genes that allow the cells to differentiate, or become different kinds of cells, with different functions. Stem cell (undifferentiated cell) research is advancing daily. Scientists will eventually be able to create different cells, grow them in a lab, and use them to cure diseases (such as diabetes), and repair injuries (such as spinal chord injuries)!
