Before mitosis, the cell creates an identical set of its own genetic information – this is called DNA replication. The genetic information is in the DNA of the chromosomes. At the beginning of mitosis the chromosomes wind up into visible objects that can be seen with a light microscope. The chromosomes are now two chromatids joined at the centromere. Since the two chromatids are identical to each other, they are called sister chromatids.
Mitosis happens in all types of dividing cells in the human body except with sperm and ova. The sperm and ova are gametes or sex cells. The gametes are produced by a different division method called meiosis.
In medicine, the hygiene hypothesis states that early childhood exposure to particular microorganisms (such as the gut flora and helminth parasites) protects against allergic diseases by contributing to the development of the immune system.
<h3>What is the role of eosinophils in hygiene hypothesis ?</h3>
Eosinophils are multifunctional granulocytes that contribute to initiation and modulation of inflammation.
- Eosinophils are extremely versatile effector cells that damage tissues or modulate the activity of other immune and stromal cells.
<h3>Why does having a parasitic worm help us ?</h3>
This is because parasitic worms have evolved strategies to block parts of the human immune system.
- These parts of the immune system, namely the eosinophils and IgE antibodies, are also the main players in allergies, IBD, and many other inflammatory diseases
