Pre-Lab Questions
1. Compare and contrast mitosis and meiosis.
Mitosis and Meiosis both include splitting DNA between new cells. They both include cell reproduction which contains chromosomes from both parents. In Mitosis the two daughter cells are identical from a single parent cell. Mitosis produces the most cells in the body. In Meiosis the daughter cells are not identical and splits the chromosomes in half which produces gametes. This makes the cells identity unique.
2. What major event occurs during interphase?
DNA replication is the major event that occurs at the completion of the three phases in the interphase.
