A Cure for Ebola, Rabies, & Other Virus Villains?
Viruses are among humanity's greatest threats and it seems like they're always one step ahead of us. But this week, biologists say that they've discovered a new weapon we can use against some of our most nefarious virus enemies - and it...

Epigenetics
You know all about how DNA bases can code for an organism's traits, but did you know there's more influencing phenotype than just the bases? Explore epigenetics with the Amoeba Sisters by learning about a few types of epigenetic marks...

TED-ED: What is epigenetics? - Carlos Guerrero-Bosagna
Here's a conundrum: Identical twins originate from the same DNA ... so how can they turn out so different - even in traits that have a significant genetic component? Carlos Guerrero-Bosagna explains that while nature versus nurture has a...

Viral Replication
Paul Andersen explains how viruses reproduce using the lytic cycle. He also shows how viruses can pick up new genetic material and how retroviruses (like HIV) can enter into the lytic cycle. He also describes the lysogenic cycle and how...

DNA, Hot Pockets, & The Longest Word Ever: Crash Course Biology
Hank imagines himself breaking into the Hot Pockets factory to steal their secret recipes and instruction manuals in order to help us understand how the processes known as DNA transcription and translation allow our cells to build proteins.

Operon
In this video Paul Andersen describes the elements of an operon. The promoter allows the RNA polymerase to transcribe the required genes. The operator and repressor regulate the expression of the genes by blocking the RNA polymerase. The...

The Central Dogma: Transcription and Translation
Mr. Andersen explains the Central Dogma of biology. He shows how DNA is transcribed to form mRNA and how mRNA is translated into a protein.
Bozeman Science
Gene Regulation
Paul Andersen explains how genes are regulated in both prokaryotes and eukaryotes. He begins with a description of the lac and trp operon and how they are used by bacteria in both positive and negative response. He also explains the...

The Secret of Life
Paul Andersen explains how the central dogma of biology explains life on our planet. He starts with a brief discussion of common characteristics of all life. He then explains how DNA is used to make proteins which in turn make you. He...

Transcription and Translation
Paul Andersen explains the central dogma of biology. He explains how genes in the DNA are converted to mRNA through the process of transcription. He then explains how ribosomes use this message to convert the mRNA to a functioning...
