CELL CYCLE (MITOSIS)

Question 1

WHY DO CELLS HAVE TO UNDERGO CELL DIVISION?

Answer 1

>CELLULAR GROWTH AND DEVELOPMENT
>CELL DIFFERENTIATION
>REPAIR AND HEALING PROCESS
>REPLICATION OF GENETIC
>PERPETUATION OF SPECIES
>CELLULAR REPLACEMENT

Question 2

IT IS KNOW AS THE LONGEST PHASE IN THE CELL CYCLE.

PHASE WHERE CELL PREPARE FOR CELL DIVISION.

INCLUDES SNA AND CELL COMPONENTS DUPLICATION.

Answer 2

INTERPHASE

Question 3

CELL INCREASES IN SIZE AND NUMBER.

Answer 3

G1 OR GAP 1 PHASE

Question 4

DOUBLING OF THE DNA.

Answer 4

S OR SYNTHESIS PHASE

Question 5

ALL CELL COMPONENTS ARE DUPLICATED AND READY TO ENTER MITOSIS.

Answer 5

G2 OR GAP 2 PHASE

Question 6

THE MITOTIC DIVISION…

Answer 6

PROPHASE -> METAPHASE -> ANAPHASE -> TELOPHASE ->

Question 7

CHROMOSOMES CONDENSED AND BECOME VISIBLE.

Answer 7

PROPHASE

Question 8

CENTROSOMES MOVES TOWARDS THE OPPOSITE POLE.

Answer 8

PROPHASE

Question 9

SPINDLE FIBERS EMERGED FROM THE CENTROSOME.

Answer 9

PROPHASE

Question 10

NUCLEAR ENVELOPE BREAKS DOWN WHILE NUCLEUS DISAPPEAR.

Answer 10

PROPHASE

Question 11

CENTROSOMES ARE ON THE OPPOSITE POLE.

Answer 11

METAPHASE

Question 12

SPINDLE FIBERS ARE ATTACHED TO THE KINETOCHORE OF THE CHROMATIDS.

Answer 12

METAPHASE

Question 13

CHROMOSOMES ARE LINED UP AT THE METAPHASE PLATE.

Answer 13

METAPHASE

Question 14

KNOWN AS THE SHORTEST STAGE OF MITOSIS.

Answer 14

ANAPHASE

Question 15

SISTER CHROMATIDS START TO SEPARATE TOWARDS THE OPPOSITE POLES.

Answer 15

ANAPHASE

Question 16

IN EACH POLE OF THE CELL THE SMAE NUMBER AND CHROMATIDS.

Answer 16

ANAPHASE

Question 17

SEPARATED SISTER CHROMATIDS ON EACH POLE STARTS TO DECONDENSE.

Answer 17

TELOPHASE

Question 18

NUCLEAR MEMBRANE AROUND EACH SET OF CHROMOSOMES REFORMS.

Answer 18

TELOPHASE

Question 19

NUCLEOLUS REAPPEAR ALONG WITH THE FORMATION OF CELL PLATE (PLANT) AND CLEAVAGE FURROW (ANIMAL).

Answer 19

TELOPHASE

Question 20

A CELLULAR DIVISION PROCESS IN WHICH DIVIDED THE CYTOPLASM OF A PARENTAL CELL INTO IDENTICAL TWO DAUGHTHER CELLS.

Answer 20

CYTOKINESIS

Question 21

SOME CELLS DO NOT UNDERGO CELL CYCLE MAYBE BECAUSE THEY WILL UNDERGO DIFFERENTIATION.

ALSO KNOW AS THE “QUIESCENT STATE” (INACTIVE STAGE).

Answer 21

G0 PHASE
