Lab7:Cell Division Flashcards
What are the 5 phases of cell division?
-interphase
-prophase
-metaphase
-anaphase
-telophase
What duplicates during the interphase?
-chromosomes
-centrosomes
-mitochondria
What disappears during the interphase?
The nucleolus
What are the three important things that occurs during prophase?
-chromosomes coil up
-centrosomes moves to pole
-nuclear membrane breaks down
During metaphase, what make spindle fibres to move chromosomes to equator?
Centrioles
Draw interphase
Draw anaphase
What are the two main step of anaphase?
-centrometer breaks down
-sister chromatids are pulled appart moving towards opposite poles
Draw prophase
What are the 4 steps of telophase?
-Nuclear membrane reforms
-chromosomes uncoil
-Nucleoli reform
-Cell divides
Draw telophase
Draw metaphase
In the interphase what is the name for chromosomes mass?
Chromatin
What held two chromatids together to form chromatid sister?
Centromere
