  2. 2. How is the number of chromosomes maintained? How are genes organized? How is a chromosome structurally designed to perform its functions?
  3. 3. Grade 7 and 8 Biology
  4. 4. Where are the chromosomes found in a eukaryotic cell? Chromosomes are made up of what substances? How will you describe the structure of a chromosome in cells at interphase stage? During cell division, what happens to the structure of chromosomes?
  5. 5. After mitosis, the 2 daughter cells contains how many chromosomes? After meiosis, the 4 daughter cells contains how many chromosomes? The single-stranded chromosome will become double-stranded during what phase of cell division?
