CELL CYCLE (MITOSIS) Flashcards
WHY DO CELLS HAVE TO UNDERGO CELL DIVISION?
>CELLULAR GROWTH AND DEVELOPMENT >CELL DIFFERENTIATION >REPAIR AND HEALING PROCESS >REPLICATION OF GENETIC >PERPETUATION OF SPECIES >CELLULAR REPLACEMENT
IT IS KNOW AS THE LONGEST PHASE IN THE CELL CYCLE.
PHASE WHERE CELL PREPARE FOR CELL DIVISION.
INCLUDES SNA AND CELL COMPONENTS DUPLICATION.
INTERPHASE
CELL INCREASES IN SIZE AND NUMBER.
G1 OR GAP 1 PHASE
DOUBLING OF THE DNA.
S OR SYNTHESIS PHASE
ALL CELL COMPONENTS ARE DUPLICATED AND READY TO ENTER MITOSIS.
G2 OR GAP 2 PHASE
THE MITOTIC DIVISION…
PROPHASE -> METAPHASE -> ANAPHASE -> TELOPHASE ->
CHROMOSOMES CONDENSED AND BECOME VISIBLE.
PROPHASE
CENTROSOMES MOVES TOWARDS THE OPPOSITE POLE.
PROPHASE
SPINDLE FIBERS EMERGED FROM THE CENTROSOME.
PROPHASE
NUCLEAR ENVELOPE BREAKS DOWN WHILE NUCLEUS DISAPPEAR.
PROPHASE
CENTROSOMES ARE ON THE OPPOSITE POLE.
METAPHASE
SPINDLE FIBERS ARE ATTACHED TO THE KINETOCHORE OF THE CHROMATIDS.
METAPHASE
CHROMOSOMES ARE LINED UP AT THE METAPHASE PLATE.
METAPHASE
KNOWN AS THE SHORTEST STAGE OF MITOSIS.
ANAPHASE
SISTER CHROMATIDS START TO SEPARATE TOWARDS THE OPPOSITE POLES.
ANAPHASE
IN EACH POLE OF THE CELL THE SMAE NUMBER AND CHROMATIDS.
ANAPHASE
SEPARATED SISTER CHROMATIDS ON EACH POLE STARTS TO DECONDENSE.
TELOPHASE
NUCLEAR MEMBRANE AROUND EACH SET OF CHROMOSOMES REFORMS.
TELOPHASE
NUCLEOLUS REAPPEAR ALONG WITH THE FORMATION OF CELL PLATE (PLANT) AND CLEAVAGE FURROW (ANIMAL).
TELOPHASE
A CELLULAR DIVISION PROCESS IN WHICH DIVIDED THE CYTOPLASM OF A PARENTAL CELL INTO IDENTICAL TWO DAUGHTHER CELLS.
CYTOKINESIS
SOME CELLS DO NOT UNDERGO CELL CYCLE MAYBE BECAUSE THEY WILL UNDERGO DIFFERENTIATION.
ALSO KNOW AS THE “QUIESCENT STATE” (INACTIVE STAGE).
