Which one of these statements is true of both mitosis and meiosis at some point during each process?

Both mitosis and meiosis happen in multiple stages. Both begin with a round of DNA replication in preparation for cell division. While the outcome of each process is different, each has an interphase where cell growth occurs. In mitosis, the end product is two cells: the original parent cell and a new, genetically identical daughter cell. Meiosis is more complex and results in four genetically diverse cells.

Not sure what you mean by this question

The answer to this will be from your lab notes/procedure. it would be best to ask another student who participated in the lab as we do not know what was done, what enzyme or if the temperature is celsius or fahrenheit. if i were to guess though i'd say the rate stopped due to enzyme denturing at high temperature
