1. Chromosomes are constructed of DNA and Protein . 2. Humans are diploid, meaning they have two sets of chromosomes numbering 46 total. 3. When chromosomes are duplicated, they look like an “X”-shaped structure. The two strands of chromosomes are attached at the Centromeres . 4. In humans and all creatures constructed of eukaryotic cells, the DNA always resides in the Nucleus . 5. The yellow and red chromosomes you constructed are similar, and therefore, both of them together are considered to be a Homologous pair. 6. In this assignment, you constructed the first phase of mitosis called Interphase . 7. During both mitosis and meiosis, chromosomes are aligned and pulled apart with the help of a cytoskeletal fiber called Mitotic Spindle .

8. Microtubules or spindle fibers attach to the centromeres of the chromosomes and pull them apart during mitosis. The microtubules radiate from structures you included in your simulation

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
