Article takes a look at how cancer develops and what's wrong with cancer cells. Also, delves into how abnormal forms of cell cycle regulators can contribute to cancer.

This cellular biology page presents extensive detail on the chemical nature of the cell membrane. Using the Chime plug-in, students can manipulate and study models of the membrane.

Resource explains apoptosis (programmed cell death) and how it is different from necrosis (cell death due to injury).

Tutorial takes a look at the three types of sexual life cycles used by different organisms: diploid-dominant, haploid-dominant, and alternation of generations.

Article explores the life cycle of a cell and delves into the phases of the cell cycle.

This informative resource features an overview of genetic material: DNA, chromosomes, genomes, homologous chromosomes, sister chromatids, and haploid/diploid.

Tutorial examines how a cell divides to make two genetically identical cells and explores the four basic phases: prophase, metaphase, anaphase, and telophase.

This article looks at a few of the most important core cell cycle regulators: proteins called cyclins, enzymes called Cdks, and an enzyme complex called the APC/C.

Learn how cells use checkpoints to regulate the cell cycle. This article provides an overview of cell cycle control, outlining the factors that influence a cell's decision to pause or progress at each checkpoint.

In this tutorial students will learn how meiosis reduces chromosome number by half and become familiar with crossing over, meiosis I, meiosis II, and genetic variation.
