During humanistic therapy sessions, patients are treated in a manner that emphasizes their innate goodness and potential. The humanistic therapist is encouraged to act in a manner consistent with the themes of unconditional positive regard, empathy, genuineness, and congruence.
Most cells are observed in Interphase, the longest part of the cell cycle. After acquiring sufficient size and ATP, the cells then undergo DNA Synthesis (replication of the original DNA molecules, making identical copies, one new molecule eventually destined for each new cell) which occurs during the S phase.
The phases of the cell cycle occur in meiosis as well as mitosis; you will see later how they differ. The length of time of the cell cycle varies among organisms and among cell types. Later in this laboratory you will calculate the length of time a cell spends in several phases of the cell cycle.
