Mitosis (stages of the cell cycle)

Stages

What are the 4 stages of Cell Cycle?

1. Gap 1 (G1) stage

2. Synthesis (S) stage

3. Gap 2 (G2) stage

4. Mitotic Phase (M stage)

Stages of Intephase

1. Gap 1 (G1) stage

2. Synthesis (S) stage

3. Gap 2 (G2) stage

These insure that the cell cycle progresses properly wherein the cells use special proteins and signaling systems

Checkpoints

What are the 3 major checkpoints?

1. Gap 1 (G1) checkpoint

2. Gap 2 (G2) checkpoint

3. Metaphase checkpoint

This is where cells accomplish most of their growth (they increase in mass and/or size)

Gap 1 (G1) stage

Gap 1 (G1) stage synthesize enough _______to make proteins

Ribosomes

This stage copies organelles needed for normal functions of DNA synthesis

Gap 1 (G1) stage

In G1 as the phase is almost done, the___________ of the cell fuse into a network of mitochondria for effective energy production for cell process

mitochondria

The length of the __________ is responsible for the difference between fast dividing cell (skin cells or blood cells) and slowly- dividing cells)

Gap 1 (G1) stage

G1 checkpoint is the____________?

Restriction point

The ____________ prevent cells from entering S phase in the presence of Dna damage and functions

G1 checkpoint

The purpose of G1 checkpoint is to inhibit the_________________

initiation of reflection

If the cell can not divide again, it enters the ?

G0

G0 is also known as the?

Resting Phase

The cell is neither dividing nor preparing to divide

G0

During the G0 checkpoint the cell_________?

Do their normal function

This stage is replication of cellular Dna

Synthesis (S) stage

this stage is very crucial part of interphase

Synthesis (S) stage

After the Dna synthesis, the cell has ________ as many chromosomes as before

Twice

After the S stage, it is now ready to move to the?

G2

The cell replenishes its energy stores and synthesizes proteins necessary for chromosome manipulation, such as kinase and histones, including the microtubules

Gap 2 (G2) stage

In G2 some cell organelles are __________ and the duplicated ____________ is dismantled to provide resources for the mitotic phase

Duplicated, Cytoskeleton

There may be additional _______during G2

Cell Growth

During G2 the chromosome start to ________and become __________

Condense, visible

Ensures that Dna replication in S phase has been successfully completed

G2 Checkpoint
