QUESTIONS ANSWERS VERIFIED A+
◉ Focusing on Cellular Structure and Function.
Answer:
◉ 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
-Most cells in the human body reside in G0
◉ -Exceptions to this are those that are (Resting in G0 phase).
Answer: -Exceptions to this are those that are metabollically active, such
as
-granulocytes
-and the epithelium of the GI tract
◉ Cell Cycling Time.
Answer: Amount of time from mitosis to mitosis
◉ Cell cycle video and image.
