Cell Cycle Quiz Preparation
Terms in this set (18)
rod-shaped structures made of DNA and proteins
a type of cell division that results in new cells with genetic material that is identical to the genetic material of the original cell
the time between cell divisions (consists of G1, S & G2)
the division of the cell's cytoplasm (happens after mitosis)
the first stage of interphase, during which cells grow to mature size
stage of interphase during which a cell's DNA is copied
the final stage of interphase during which a cell makes final preparations from division
stage of the cell cycle in which cells DO NOT copy their DNA and DO NOT prepare for cell division
first phase of mitosis - chromosomes shorten and thicken - nuclear membrane breaks down - spindle fiber network form
chromosomes are easy to identify and are lined up at the center of the cell
chromatids separate at the centromere and begin slowly moving towards opposite poles
chromosomes have reached opposite ends of the cell - spindle fibers disassemble - chromosomes begin to uncoil
Chromatin is not condensed. Chromosomes are not visible.
Chromatin condenses, chromosomes are clearly visible
Chromosomes are lined up in the middle of the cell
Sister chromatids are pulled to opposite poles
Chromosomes are in to completely separate piles at the poles of the cell.
Chromosomes are uncoiled and the cytoplasm is being pinched in half
