The Normal Cell Cycle - CORRECT ANSWER--The cell cycle refers to the
ordered seres of processes of DNA replication and mitosis, or cell division
,Lesson 1: Foundations to Set the Stage - CORRECT ANSWER-
Focusing on Cellular Structure and Function - CORRECT ANSWER-
-Cell nucleus regulates these processes by gathering and processing complexes
molecular information
Interphase and Mitotic Phase - CORRECT ANSWER-Cell division produces two
identical cells through these two major phases
During interphase: - CORRECT 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) - CORRECT 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) - CORRECT 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) - CORRECT 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 - CORRECT ANSWER--
G1 checkpoint
-S Phase
-G2 checkpoint
-M phase
Restriction Point - CORRECT 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
