What happens in INTERPHASE?
|
- This is the normal state of a cell. We suppose when it comes to cell division, you could call this the resting state. It's just going about its daily business of surviving, making sure it has all of the nutrients and energy it needs. It's also getting ready for another division that will happen one day. It is duplicating its nucleic acids, so when it's time for prophase again, all the pieces are there

What is the definition of mitosis?
|
The big thing to remember is that mitosis is the simple duplication of a cell and all of its parts. It duplicates its DNA and two new cells have the same pieces and genetic code. Two identical copies come from one original. Start with one; get two that are the same. The point has been made.

What happens in telophase?
|
- Now the division is finishing up. This is the time the cell membrane closes in and splits the cell into two pieces. You have two separate cells each with half of the original DNA.

What are the five stages of mitosis?
|
PROPHASE -- METAPHASE -- ANAPHASE -- TELOPHASE -- INTERPHASE
|
|
|
What happens in PROPHASE?
|
- A cell gets the idea that it's time to divide. First it has to get everything ready. You need to duplicate DNA, get certain pieces in the right position (CENTRIOLES) and generally prepare the cell for the process of mitotic division

What happens in METAPHASE?
|
- Now all of the pieces are aligning themselves for the big split. DNA is lined up along a central axis and the centrioles send out specialized tubules that connect to the DNA. A little point... The DNA (chromatin) has now condensed into chromosomes. Two strands of a chromosome are connected at the center with something called a CENTROMERE. The tubules actually connect to the centromere, not the DNA.

|
|
What happens in ANAPHASE?
|
- Okay, here we go! The separation begins. Half of the chromosomes are pulled to one side of the cell, half go the other way. When the chromosomes get to the side of the cell, it's time to move on to Telophase.
