The video explains the various aspects of reproduction in biology, including sexual and asexual reproduction. It describes the differences between these two types of reproduction. The video also explains the process of meiosis and...

Peptidyl Transferase/Ribosome Physiology, Biochemistry, and Mechanism

Rotifers exist in a wide range of shapes, from globular, sac-like floaters to elongated worm-like swimmers and creepers to sessile types. In this video we'll focus on the four major clades of this phylum - though there is debate around...

Now 13 years old, 23andMe is aiming to expand its revenue stream to incorporate genetic data into drug development. Its co-founder and CEO lays out her vision to expand beyond genetic-testing kits.

This exciting program takes a glimpse at some of the amazing advances in modern genetics. Starting with the discovery of DNA, students will be exposed to advances such as the creation of recombinant DNA, vaccines, the human genome...

This video explores the Central Dogma of Molecular Biology (Transcription & Translation) at an introductory or general biology level.

We learned about gene expression in biochemistry, which is comprised of transcription and translation, and referred to as the "central dogma" of molecular biology. But how is this process regulated? How does a cell know which genes to...

This is a video that explains the two types of reproduction: sexual and asexual reproduction. The video begins with an introduction on the importance of reproduction for organisms, and then focuses on sexual reproduction. The video also...

A bracelet burglar is on the loose! Sally puts on her detective hat. If she can solve the crime, maybe she’ll get a voucher to use at Tiffany & Chro. This lesson will begin our review of prokaryotic and eukaryotic cells, focusing on...

In this video we are going to look at what happens when a virus invades a host cell. You should already have an understanding of what viruses are.

This video is a lesson on genetics, specifically focusing on the inheritance of traits from parents to offspring. The teacher explains the concept of genetics and introduces Gregor Mendel, the father of genetics. The video also discusses...

We've established that the basic unit of life is the cell, and that the simplest forms of life are just one cell. The earliest unicellular organisms were prokaryotic, and there are many prokaryotic organisms still around today, including...
