Lesson 1: Foundations to Set the Stage: Focusing on Cellular Structure and Function: 1. The Normal Cell Cycle: -The cell cycle refers to the ordered seres of processes of DNA replication and mitosi... s, or cell division -Cell nucleus regulates these processes by gathering and processing complexes molecular information 2. Interphase and Mitotic Phase: Cell division produces two identical cells through these two major phases 3. During interphase:: Cell grows and DNA is replicated through the following three steps: 1: First growth phase (G1 or first gap) 2: Synthesis phase (S phase) 3:Mitotic Phse (M phase) 4. First Growth Phase (G1 or first gap): -cells increase in size -reproduce RNA -"quality assurance" test that the cell will be ready to synthesis DNA -Length of time is variable, can be from hours to days 5. Synthesis Phase (S phase): -DNA replicates -Results in the formation of identical pairs of DNA (chromatids) -which are attached a t the centromere -lasts 2-10 hours 6. Mitotic Phase (M phase): -Replicated chromosomes are aligned, separated, and move into 2 new, identical daughter cells -takes about 30-60 minutes [Show More]
