Telophase/Cytokinesis Describe the SHAPE and AMOUNT of DNA in the cell in the following stages: Stage Amount – Shape – What is happening to the DNA? G1 S G2 Prophase Metaphase Anaphase Telophase Cytokinesis circle one One copy circle one Chromatin Two copies Chromosome One copy Chromatin Directing cell’s activities Two copies Being duplicated through replication, copies are held by Chromosome centromere One copy Chromatin Two copies Chromosome One copy Chromatin Two copies Chromosome One copy Chromatin Two copies Chromosome One copy Chromatin Two copies Chromosome One copy Chromatin Two copies Chromosome One copy Chromatin Two copies Preparing the cell for mitosis Condenses into chromosomes Line up across the middle of the cell Sister chromatids are pulled apart to opposite ends of the cell DNA stretches out, starts to look like chromatin again DNA looks like chromatin, beings directing cell’s activities Chromosome again Label the Diagram below:
