During interphase

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

• 2 new nuclei form

• 2 new identical cells are created

• DNA gets copied

Uncontrollable cell growth is known as _____

• obesity
• cancer
• diabetes
• hepatitis

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.
