Materials Formed Prior to Mitosis

• Chromatin: DNA wrap around 8 HISTONE PROTEINS
• Chromatin: only composed of DNA material around 6 meters
• Chromatid: one of 2 parts of duplicated chromosome attached at the point of centromere
• Chromatid: half part of the chromosome
• Chromosome: condensed form of DNA
• Shorter telomere means what?

  older age
• What is the central part of the chromosome?

  centromere
• Centromere: Primary constriction where chromatids are attached together
• What surrounds the centromere?

  Kinetochore
• Kinetochore: forms on a chromatid during cell division, allowing it to attach to spindle fiber
• What is the area where microtubule attaches that help pull the chromosome apart?

  Kinetochore
• Centrosome: Microtubule organizing center formed during the S phase
• Centrosome: has the ability to duplicate itself
• Centrosome divide during which phase?

  Interphase
• How many pairs of centrioles do centrosome have?

  2
• Centriole: 1 part of the centrosome
• Mitotic spindle: Responsible in moving chromatids in separate poles
• Microtubules: attached to kinetochore
