Preparation and Staining of Mammal Cells to View Sister Chromatids

Some genetic conditions occur without being inherited. The distinction becomes the focus of the lesson. It details the process of cell division that results in trisomy on various chromosomes. A worksheet highlights the results including...

Take your advanced biology learners across the great divide: where cells divide, that is! Although it was created as a chapter reading guide, having your class complete this worksheet is not only appropriate, but also highly valuable in...

Cell division and all the biological aspects of activation and chemical signals are detailed here. Cyclin, G phases, cell growth, and cancer checkpoint control systems are explained and the triggers listed. The slides are very clear and...

What did one cell say to his sister when she stepped on his toe? Mitosis! The video details the process of using division to multiply that is better known as mitosis. It includes the four steps of mitosis: prophase, metaphase, anaphase,...

Based on current scientific knowledge, all cells come from preexisting cells. Scholars learn about cell division, cell replication, mitosis, meiosis, and more with a PowerPoint. It describes the differences between prokaryotes and...

Students create and test a hypothesis about cell division. After observation of Frog Egg cell division, students write obervations and refine process and hypothesis. The use of scientific method, group work and inquiry are fostered by...

This animated explanation introduces the concept of mitosis by reviewing the research of Walther Flemming.

Slideshow of mitosis and meiosis side-by-side. It is a summation of the two processes and the differences between them are clear.

See how sister chromatids separate to form gametes during the stages of meiosis including prophase II, metaphase II, anaphase II, telophase II. [10:57]

Explains what chromosomes are, how chromatids are related to them, and how they function together during cell division.
