Cell Cycle

Question 1

It refers to the series of events that take place in a cell, resulting in the duplication of DNA and division of cytoplasm and organelles to produce two daughter cells.

Answer 1

Cell cycle

Question 2

Stages of cell cycle

Answer 2

G1 phase, S(synthesis) phase, G2 phase, M(mitosis) phase, cytokinesis phase

Question 3

It is the time during which the cell prepares for division by undergoing both cell growth and DNA replication.

Answer 3

Interphase

Question 4

The cell grows and makes a new set of organelles and proteins for the daughter cells.

Answer 4

G1 (gap 1) phase

Question 5

Cellular DNA is replicated and the two daughter cells each get one set of DNA. Genetic material is checked too

Answer 5

S(synthesis) phase

Question 6

Cell growth continues and there is synthesis of special proteins in preparation for mitosis.

Answer 6

G2 (gap 2) phase

Question 7

The cell splits its DNA and organelles into two identical daughter cells

Answer 7

M(mitosis) phase

Question 8

The cell will completely divides into two daughter. cells.

Answer 8

Cytokinesis phase

Question 9

a process that is highly sensitive to errors which may lead to the death of cells if an abnormality is allowed to propagate. Thus, it is only important to have checkpoints that assess the progress of the cell cycle

Answer 9

Cell cycle/ cell cycle checkpoint

Question 10

The cell cycle is controlled by ? that either promote the process or stop it from progressing.

Answer 10

Regulator molecules

Question 11

TWO GROUPS OF PROTEINS

Answer 11

•Cyklins
•Cyklin-dependant kinases (Cdks)

Question 12

This checkpoint makes the decision of whether the cell will divide.

If conditions are favorable for division and the cell is healthy and large enough, and has adequate energy reserves, certain proteins will stimulate the cell to begin the S phase

Answer 12

G1 checkpoint

Question 13

The cell can halt the cycle and attempt to remedy the problematic condition, or the cell can advance into Go (inactive) phase and await further signals when conditions improve.

Answer 13

G1 checkpoint

Question 14

The role of this checkpoint is to ensure that all the chromosomes have been accurately replicated without mistakes or damage.

Answer 14

G2 phase

Question 15

The role of this checkpoint is to ensure that all the chromosomes have been accurately replicated without mistakes or damage.

Answer 15

G2 checkpoint

Question 16

If the DNA has been correctly replicated, cyclin dependent kinases (CDKs) signal the beginning of mitotic cell division.

Answer 16

G2 phase

Question 17

This checkpoint occurs near the end of the metaphase stage of mitosis.

This checkpoint is also known as the spindle checkpoint because it determines whether all the sister chromatids are correctly attached to the spindle microtubules.

Answer 17

M checkpoint

Question 18

M checkpoint also called?

Answer 18

Spindle checkpoint
