Draw one eukaryotic chromosomes as it would appear during interphase, during each stages of mitosis, during cytokinesis. and also draw and label the nuclear envelope and any microtubules attaches to the chromosomes.
Let’s model mitosis. Focus on drawing the cell nucleus taking care to model the number and location of chromosomes. Although the chromosomes are only visible in each stage, draw them in all stages for clarity sake.
Draw a 2n=4 cell at G1 of interphase.
Draw the same cell at the start of prophase.
Draw the same cell at metaphase.
Draw the cell(s) that result at the end of cytokinesis.
1. Draw and label a cell with the following organelles: nucleus, rough ER, Golgi apparatus, mitochondria, and centrioles.
2. Draw and label a cell with four chromosomes in interphase and each stage of mitosis.
