Interphase(Before and After)
What are the three parts of Interphase?
G1, S, and G2
How much time is spent in Prophase?
Up to half of the time mitosis takes to finish.
Is this phase the longest or the shortest?
Usually the shortest.
What are the sister chromatids considered when Anaphase begins?
They are considered individual chromosomes.
What happens after Telophase?
Mitosis (without cytokinesis) is complete.
What is Interphase?
The life of a cell as one cell division after another separated by an in-between period of growth.
What happens in Prophase?
The genetic material inside the nucleus condenses and the duplicated chromosomes become visible. A spindle also forms outside the nucleus.
What happens in Metaphase?
The centromeres of the duplicated chromosomes line up across the center of the cell. Spindle fibers connect to the centromere of each chromosome to the two poles of the spindle.
What happens during the Anaphase?
The chromosomes separate and move along spindle fibers to opposite ends of the cell. This ends when the chromosomes are separated into two groups.
What happens during Telophase?
The distinct and condensed chromosomes begin to spread into a tangle of chromatin. A nuclear envelope re-forms around each cluster of chromosomes. Also, the spindle breaks apart and a nucleolus becomes visible.
What happens in at least one of the processes...
G1: Cells increase in size and synthesize new proteins and organelles
S: DNA is synthesized when the chromosomes are replicated
G2: The organelles and molecules needed for cell division are produced

metaphase
What happens after all phases are complete in cell division?
One of the cells leaves the cycle while the other cell waits for a signal to start the cycle again.
What is cytokinesis?
the splitting of cytoplasm
Is cytokinesis a phase of cell division?
No
What happens in cytokinesis?
Two daughter cells are made
What is the name of the middle of where the cell splits?
the cleavage furrow
What do Cyclins do?
They seem to regulate the cell cycle.
When were Cyclins first discovered?
the early 1980's
Where are the cyclins the most concentrated?
The S Phase
How many different cyclins are there?
4
