In eukaryotic cells, the nucleus divides before the cell itself divides. The process in which the nucleus divides is called mitosis. Before mitosis occurs, a cell’s DNA is replicated. This is necessary so that each daughter cell will have a complete copy of the genetic material from the parent cell. How is the replicated DNA sorted and separated so that each daughter cell gets a complete set of the genetic material? To understand how this happens, you need to know more chromosomes.
• Describe chromosomes and their role in mitosis.• Outline the phases of mitosis.
ENGAGE 10min
Study the 3D model “Mitosis” in the Lifeliqe Human Biology library. Then, formulate answers to these questions:
• How does the cell replicate itself before dividing?• What are the role of chromosomes?
EXPLORE 20min
Read “Chromosomes and Mitosis..”www.ck12.org/section/Chromosomes-and-Mitosis...
Experiment with the cK-12 PLIX “Mitosis and Cytokinesis: Wound Healing Process.”www.ck12.org/assessment/tools/geometry-tool/plix.html?eId=SCI.BIO.244...
EXPLAIN 15min
This is a demo. The interactive 3D content is available in the full Lifeliqe app. Get it here.
EXTEND / ELABORATE 15min
Take what you have learned and see it in authentic contexts..
Read “Hmmm, Something’s Wrong.”www.ck12.org/biology/Cell-Division/rwa/Hmmm-Somethings-Wrong
Take the following quiz to assess what you have learned.
