Cell Size and Cell Cycle Mitosis

During prophase

• DNA lines up in the middle of the cell and DNA attaches to spindle fibers

• DNA condenses into chromosomes, centrioles and spindle fibers appear

• 2 new identical cells are created

• DNA gets copied

During metaphase

• DNA lines up in the middle of the cell and DNA attaches to spindle fibers

• centrioles and spindle fibers appear

• 2 new identical cells are created

• DNA gets copied

During anaphase

• DNA lines up in the middle of the cell and DNA attaches to spindle fibers

• centrioles and spindle fibers appear

• Each DNA gets pull to the opposite sides of the cell

• DNA gets copied

The process of mitosis starts with one parent cell, and results in two identical daughter cells. During ​ (a)   , the cell elongates and pinches inward, while the nuclear envelope re-forms. In ​ (b)   , the chromatids begin to pull apart and move to opposite poles. During ​ ​ (c)   , the nuclear envelope begins to break down, and the chromosomes fully condense. In ​ (d)   , the centrioles migrate to opposite ends of the cell, while the chromosomes line up in the center, ready to divideA

Why would it be important to replicate DNA before a cell divides in mitosis or meiosis?

• In order for genetic information to be transferred into daughter cells.

• In order for the cell to be able to increase in size.

• In order for the DNA to be contained in the nucleus.

• In order for the cell to re-order the DNA sequencing in the new cells.
