Cell Cycle and Division starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Cell Cycle and Division.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
A cell with 12 chromosomes undergoes mitosis. How many chromosomes will each daughter cell have?
A diploid cell with 8 chromosomes undergoes meiosis. How many chromosomes will each gamete have?
A mutation in a gene controlling the G1 checkpoint leads to cells dividing uncontrollably. What disease could this result in?
Describe the main events that occur during the G1 phase of the cell cycle.
Describe what happens during prophase of mitosis.
