Cell Cycle, Mitosis and Meiosis
Paul Andersen explains how the cell cycle is used to create new cells. The creation of identical diploid daughter cells, through mitosis, is described. The creation of unique haploid daughter cells, through meiosis is also described. The...
Professor Dave Explains
The Cell Cycle and its Regulation
Your cells have to divide when you're growing, to heal wounds, and to replace dead cells. But how do cells know when to divide and when not to divide? We can't have cells just growing willy-nilly! That's what cancer is, and that's bad....

Eukaryotic Cell Cycle Regulation in 5 minutes
The cell cycle is a highly regulated process of eukaryotic cell division involving interphase (G1, S, G2 phases) for growth and DNA replication, followed by mitosis for chromosome segregation and cell division. Progression through the...

TED-Ed: The cancer gene we all have - Michael Windelspecht
Within every cell in our body, two copies of a tumor suppressor gene called BRCA1 are tasked with regulating the speed at which cells divide. Michael Windelspecht explains how these genes can sometimes mutate, making those cells less...

Cell Cycle Regulators & Tumor Suppressor Genes | Proto-oncogenes & Oncogenes
In this video, we discuss the difference between proto-oncogene and oncogene AND the meaning of tumor suppressor genes. We also explore how dysfunction in any of these can lead to cancer.

Glycolysis Pathway | Enzymes, Regulation and Products
Lesson on the Glycolysis pathway. In this video, I explain the glycolysis pathway (pathway involved in breakdown of glucose) starting with glucose uptake into the cell, glucose entrapment via hexokinase/glucokinase, examining the energy...
Crash Course
Blood, Part 2 - There Will Be Blood: Crash Course A&P
It's time to start talking about some of the terrible things you can do to your own body, like blood doping. We'll start by explaining the structure and function of your erythrocytes, and of hemoglobin, which they use to carry oxygen....

The Nuclear Pore Complex: Nuclear Import, Export, & RAN
In this video, we discuss the mechanisms by which proteins are targeted to the nucleus (import) and moved from the nucleus to the cytoplasm (export). Collectively, nucleocytoplasmic transport is regulated by the nuclear pore complex and...

Genetics Preview
Paul Andersen previews the information in the genetics unit. He defines the central dogma of biology and explains how DNA creates an RNA transcript that is used to translate proteins. He differentiates between mitosis and meiosis. He...

SOS repair of DNA
The SOS response is a bacterial mechanism activated by DNA damage, involving the RecA protein and regulated by the LexA repressor. Upon DNA damage, RecA binds to single-stranded DNA, becomes activated, and promotes LexA self-cleavage,...

Cell Cycle, Mitosis and Meiosis
If a cell is unable to regulate the cell cycle, wild cell growth may occur, leading to cancer. Learners explore the cell cycle, using mitosis and meiosis to create new cells. Learners walk, simply, through each phase of the cell cycle:...
