I m not sure if he specifically wants me to focus on Down Syndrome or genetic diseases in general. I know DS is caused by nondisjunction during meiosis, not mitosis and occurs more-so in meiosis I than II. Can it occur in mitosis? If the answer to this prompt would be meiosis, why is that? It was discovered in , by Rudolf Virchow, that new cells can only arise from previously existing cells. This is done in two ways: mitosis and meiosis. Somatic body cells divide exclusively by mitosis followed by cytokinesis, while germ cells produce gametes by the process of meiosis.

This occurrence is known as nondisjunction, and it is often triggered by a lapse during a mitotic checkpoint. Should nondisjunction occur during meiosis, the resulting egg or sperm cell will have an incorrect number of chromosomes; if this sex cell is then fertilized, the fetus will have a chromosomal abnormality. Protein synthesis lecture video Answer the following questions pertaining to this lab: 1. Define meiocyte, sporocyte, meiospore, and microspore. Meiocyte: It is a type of cell which differentiate into gamete through meiosis. Sporocyte: It is a diploid cell in spore bearing plant which produces four haploid spores through meiosis.

The parent cell produces four haploid daughter cells. Prior to both mitosis and meiosis, the chromosomes in the nucleus are replicated. The nucleus then divides. Nuclear division is usually followed by division of the cytoplasm. In mitosis, there is one such division. In meiosis, diploid parent cells divide and produce the gametes or spores that give rise to new individuals. AP Lab 3 — Mitosis and Meiosis.

There are two parts to each assembly line: the first builds According to the cell theory of biology, all cells arise from pre-existing cells. In eukaryotes, this generally occurs by the process of mitotic cell division, which involves the separate but often coordinated processes of cytokinesis division of the cytoplasm and organelles and mitosis division of the nucleus and associated DNA.
