Mitosis Lab Report
Introduction:
Mitosis occurs in all eukaryotic cell tissues and produces genetically identical daughter cells with a complete set of chromosomes. In humans, mitosis produces somatic cells that are diploid, which means they contain two non-identical copies of each of the twenty-three chromosomes. One copy is derived from the person's mother and the other from the person's father.
Meiosis, on the other hand, occurs only in testis and ovary tissues, producing sperm and ova (eggs). The gametes that are produced by meiosis in humans are haploid, containing only one copy of each of the twenty-three chromosomes. Because of recombination and independent assortment of parental chromosomes, the daughter cells produced by meiosis are not genetically …show more content…
It is generally followed immediately by cytokinesis, which divides the nuclei, cytoplasm, organelles and cell membrane into two daughter cells containing roughly equal shares of these cellular components. Mitosis and cytokinesis together define the mitotic (M) phase of the cell cycle, the division of the mother cell into two daughter cells, each with the genetic equivalent of the parent cell.
In simple terms, mitosis is the process where non sex cells reproduce by duplicating DNA and dividing into two identical cells. Each cell has a complete set of chromosomes. These cells are called diploid (double) as they have twice as many chromosomes as the two cells that join via fetilization to form it.
Meiosis is the process where sex cells (called gametes which carry the genetic material for deteriming the sex of an offspring) reproduce by duplicating DNA and diving into four new cells that have half (haploid) the genetic material of the original cell.
Both mitosis and meiosis are mechanisms that describe cell division. The difference is particularly noticeable when one looks at the DNA in the cell's nucleus. After mitosis, each of the daughter cells will have exact same DNA strands, while after meiosis each daughter cell will only have half of the DNA strands. (Sometimes the division is not exactly half/half, but that is not important for …show more content…
I chose a simple procedure that can be carried out using materials that are easily found in the home. The exception is Toluidine blue which however can be bought in shops that sell materials for chemical and biological laboratories. Almost all microscopists have this dye or another nuclear colorant. Colouration of the mitotic spindle would also be useful to more fully illustrate the phenomenon of cellular duplication. However, another colorant would be necessary, not blue but instead red or orange. This simple experiment can help give an idea of the complexity, of the precision and of the fascination of the processes that sustain the life of living
