PROKARYOTIC CELL DIVISION DIVIDE BY A PROCESS CALLED_____? |
BINARY FISSION |
|
|
WHAT IS THE FIRST STEP OF BINARY FISSION? |
DNA COPIES ITSELF |
|
|
WHAT IS THE SECOND STEP OF BINARY FISSION? |
CELL BEGINS TO DIVIDE |
|
|
WHAT IS THE THIRD STEP OF BINARY FISSION? |
CELL SPLITS INTO 2 IDENTICAL CELLS |
|
|
WHAT IS EUKARYOTIC CELL DIVISION CALLED? |
IT GOES THROUGH THE CELL CYCLE |
|
INTERPHASE |
STEP 1: TIME BETWEEN CELL DIVISION |
|
|
INTERPHASE DESCRIPTION OF STEPS |
G2-CELL GROWS s-dna copies itself (dna synthesis) G2- CELL PREPARES FOR DIVISION CHROMATIN-PRESENT IN NUCLEUS LONGEST STAGE OF CELL CYCLE CELLS CAN ALSO EXIT CELL CYCLE-USUALLY DURING G1 ONCE THESE CELLS REACH MATURITY THEY DO NOT COPY DNA AND DO NOT DIVIDE |
|
PROPHASE |
*chromatin coils into chromosomes* |
|
METAPHASE |
SHORTEST STAGE OF MITOSIS *CHROMOSOMES LINE UP AT EQUATOR (MIDDLE) OF CELL* |
|
ANAPHASE |
CHROMOSOMES SPLIT *SISTER CHROMATIDS ARE PULLED TOWARDS OPPOSITE POLES BY RETRACTING SPINDLE FIBERS* |
|
TELOPHASE |
-SPINDLE FIBERS DISASSEMBLE -CHROMOSOMES UNCOIL AND BECOME CHROMATIN -NUCLEAR ENVELOPE AND NUCLEUS REAPPEAR *CYTOKINESIS(CYTOPLASM DIVIDES)*
|
|
|
WHAT IS THE SIGNIFICANCE OF MITOSIS? |
WHEN COMPLETE WITH THE CELL CYCLE, THERE ARE 2 NEW DAUGHTER CELLS, WHICH ARE GENETICALLY IDENTICAL, AND ARE RELATIVELY THE SAME SIZE |
|
|
WHY TYPE OF CELLS DOES MITOSIS FORM? |
FORMS SOMATIC CELLS THAT ARE DIPLOID |
