How do we know DNA is the genetic material?
By Anonymous Student
How do we know that DNA is the hereditary material? This video outlines three main experiments that contributed to the knowledge that DNA transfers information from one generation to the next, discovered years before the complete structure of DNA was even known.

What is the difference between DNA and RNA?
By Jack Toor
The central dogma of biology hints that DNA is for long-term storage of information and RNA is for quickly making lots of copies of a gene when needed for expression. But what biochemical differences exist between DNA and RNA to make these roles happen?

Why are the Okazaki fragments important?
By Lina Jeffery
What exactly are Okazaki fragments and why are they important in our cells? They actually play a fundamental role in the replication of our DNA, as they efficiently and effectively aid in lagging strand replication. Beyond that, their discovery in 1966 is attributed to a unique team with an intriguing story.

How are chromosome ends maintained?
By Lauren Martin
This video discusses the significance of telomeres and telomerase. Specifically, it summarizes how they work, why they are important, and when problems can arise, especially in cancer. It also discusses their association with aging.

What is the mechanism of transcription termination in Eukaryotes?
By Raegan Blue
This video describes the mechanism and impact of transcription termination in Eukaryotes and explains the torpedo model of this process.

What is the genetic code? How was it deciphered?
By Anonymous Student
This video is about the genetic code and how it was discovered. It explains how to use the genetic code table when reading mRNA. It also talks about the experiments of Nirenberg, Khorana, and Leder that led to the genetic code’s discovery.

How to predict protein sequence based on mRNA sequence?
By Anonymous Student
mRNA, tRNA and ribosomes are involved in the process of translation, or protein synthesis. By understanding the genetic code and important features about the way mRNA is read, protein sequences can be predicted.

What are the impacts of different types of point mutations?
By Anonymous Student
What are point mutations? This video introduces the basics of point mutations, which can affect both DNA and RNA. Point mutations can affect the sequence of DNA and RNA, and the ones that will be covered in these videos are nonsense, missense, silent, insertion, and deletion mutations.

How is the Lac operon regulated? 
By Amber Beilfuss
What is the lac operon? This video explores both the structural components of the lac operon as well as the regulatory components. Additionally, it describes the different scenarios in which the lac operon is active or inactive within the cell.

How is the Lac operon regulated?
By Madaline E McPherson
This video explains the E. coli lactose operon and the role of its components, including the repressor, operator and activator.

How are eukaryotic genes regulated?
By Anonymous Student
This video introduces broad themes in eukaryotic gene regulation, including nucleosomes, enhancers, insulators, and a look back at the Gal system in yeast. To illustrate the most important polymer in life, it does it all with the help of polymer clay models!

What is genomic imprinting? 
By MacKenzie Hagood
This video uses beautiful animations to explain the process of genomic imprinting.

What is microRNA and how does it work?
By Jessica Henry
This video introduces the production and purpose of miRNA. It discusses the functions of proteins including Drosha, Dicer, and RISC. The produced miRNA functions in posttranscriptional regulation by blocking translation or cutting mRNA to silence gene expression.

What is microRNA and how does it work?
By Mira Bhandari
microRNAs are a family of small, non-coding RNA molecules that have garnered increasing attention in the last 30 years. Their functionality as post-transcriptional off-switches make them important regulators of gene expression. This ability also suggests that microRNA therapies may have exciting clinical promise.
