Khan Academy: Cell Signaling in Yeast Reproduction

Did you know that yeast use a mating factor pathway to to signal to reproduce sexually? This video will review over the process of how two haploid yeast cells combine to form a diploid cell. A mating factor is secreted by yeast cells...

Test your knowledge on cell signaling with this multiple choice quiz.

Article takes a look at how unicellular organisms "chat" with one another using chemical signals. It examines yeast mating types, bacterial quorum sensing, and biofilms.

This Khan Academy tutorial will enrich study on the different types of proteins that exist on the cell membrane. [8:11]

A video explaining embryonic and somatic stem cells by overviewing early development of an embryo. Also discussed is the reasons why embryonic stem cell research can be controversially. [19:54]

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.

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 about what happens to the cell during interphase in this video. Video will review how the cell prepares for cell division including chromosome changes, centromeres, and many more. [8:27]

A video discussing the similarities and differences between the processes of mitosis and meiosis. Learn how mitosis results in two identical diploid cell while meiosis results in four haploid genetically different cells. [5:50]

Review over the checkpoints of the cell cycle in this video. Understand the proteins that play in the role in making sure the cell cycle works correctly. [4:09]
