1. Lesson 1 Foundations to Set the Stage
Answer
2. Focusing on Cellular Structure and Function
Answer
3. The Normal Cell Cycle
Answer -The cell cycle refers to the ordered seres of processes of DNA replication
and mitosis, or cell division
-Cell nucleus regulates these processes by gathering and processing complexes
molecular information
4. Interphase and Mitotic Phase
Answer Cell division produces two identical cells through these two major phases
5. During interphase
,Answer 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)
,6. First Growth Phase (G1 or first gap)
Answer -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
7. Synthesis Phase (S phase)
Answer -DNA replicates
-Results in the formation of identical pairs of DNA (chromatids)
-which are attached a t the centromere
-lasts 2-10 hours
8. Mitotic Phase (M phase)
Answer -Replicated chromosomes are aligned, separated, and move into 2 new,
identical daughter cells
-takes about 30-60 minutes
9. Major points of cell regulation are entry and exit from
Answer -G1 checkpoint
3 N/ N61
, -S Phase N
4 N/ N61
