Bi Sci 001 Monday March 22, 1999 Announcements: Review Session tonight at 110 Wartick Lab, from 6:30-7:30 Lecture notes: Mitosis Cell Division Prokaryotes : (no nucleus) divide by binary fission. One piece of DNA divides, there are no organelles to separate. Mitosis : the mechanism by which eukaryotic cells of the new generation receive a duplicate of the parental DNA. Cytokinesis : dividing up of the cytoplasm. This happens in late anaphase or telophase. Chromosomes : pieces of DNA with attached DNA proteins. A cell of a species can have as many as 1,000. Usually that are 10-50. Sister Chromatids : duplicated DNA. Centromere : the area where sister chromatids are attached. Condensed chromosome : a chromosome which has coiled itself into a compact unit prior to separation of sister chromatids. (mitosis/meiosis). Kinetochores : Chromosomal proteins that form on the sides of each centromere. They become attached to microtubules that help move chromosomes during the nuclear division processes (mitosis/meiosis). Cell Cycle Interphase has 3 parts: G 1 a period of growth and synthesis of new cell parts. S "sythesis" phases - the DNA replicates G 2 preparation for mitosis

    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.
