Questions And Answers
Lesson 1: Foundations to Set the Stage
Focusing on Cellular Structure and Function -
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
,Interphase and Mitotic Phase - ANSWER ✔✔Cell
division produces two identical cells through these
two major phases
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)
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
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
Mitotic Phase (M phase) - ANSWER ✔✔-Replicated
chromosomes are aligned, separated, and move into
2 new, identical daughter cells
-takes about 30-60 minutes
Major points of cell regulation are entry and exit
from - ANSWER ✔✔-G1 checkpoint
, -S Phase
-G2 checkpoint
-M phase
Restriction Point - ANSWER ✔✔-The transition from
the resting phase into an actively dividing phase (G0-
G1) is a point where cellular transformation can
occur
-During this time, cells pass through a transition
phase known as a restriction point
-Extracellular growth factors trigger reentry into G1,
and GF are required to send the cells past the
restriction point, or the point of no return
G0 Phase (resting phase) - ANSWER ✔✔-After mitosis,
cells may enter back into the G1 phase or go into a
resting phase, known as G0
