QUESTION 1 vc




The Normal Cell Cycle
vc vc vc




ANSWER

-The cell cycle refers to the ordered seres of processes of DNA replication and mitosis, or cell division -
vc vc vc vc vc vc vc vc vc vc vc vc vc vc vc vc vc vc



Cell nucleus regulates these processes by gathering and processing complexes molecular information

QUESTION 2 vc




Interphase and Mitotic Phase vc vc vc




ANSWER

Cell division produces two identical cells through these two major phases

QUESTION 5 vc




Synthesis Phase (S phase) vc vc vc




ANSWER

-DNA replicates -Results in the formation of identical pairs of DNA (chromatids) -

QUESTION 6 vc




Mitotic Phase (M phase) vc vc vc




ANSWER

-Replicated chromosomes are aligned, separated, and move into 2 new, identical daughter cells -

QUESTION 8 vc




Restriction Point vc




ANSWER

-The transition from the resting phase into an actively dividing phase (G0-
vc vc vc vc vc vc vc vc vc vc vc



G1) is a point where cellular transformation can occur -
vc vc vc vc vc vc vc vc vc



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 restri

ction point, or the point of no return

QUESTION 9 vc




G0 Phase (resting phase)
vc vc vc




ANSWER

, -After mitosis, cells may enter back into the G1 phase or go into a resting phase, known as G0 -

Most cells in the human body reside in G0

ANSWER

-The cell cycle is carefully controlled through a series of checkpoints -
