Mitosis is the process in which a cell breaks apart its chromosome to eventually produce two identical daughter cells. The cell spends 10% of its time in mitosis. The cell goes through four stages in order to complete this task. The stages are Prophase‚ Metaphase‚ Anaphase and Telophase. Mitosis only occurs in eukaryotic cells and the process is different for different species. Mitosis is fast and very complex. The first phase is Prophase. In prophase‚ the chromosomes the chromosomes start to

PRACTICAL 2 Title: Modelling of mitosis Objectives: To represent the pairs of homologous chromosomes by using pairs of model chromosomes. Introduction: Materials: 1. Noodles 2. Cutter Method: 1. The pair of model chromosomes is used to demonstrate how the two chromosomes line up at the beginning of mitosis. 2. After that the way of the sister chromatids of each chromosome separate into two separate chromosomes is demonstrated. 3. The spindle fibers that pull the sister chromatids apart is represented

percentage of GDP decreased by 16.15% during last year’s recession‚ indicating skepticism in Country A’s overall economic stability. In this type of situation‚ Country A would be less likely to undergo a recession if they had enough reserves to make up for significant loss of investment. Unfortunately‚ reserves are lower than desired and create no financial backup for a Country already experiencing a recession. Country B will not undergo a currency crisis in the near future.
