Aminoacyl tRNA Synthetase: Part 1

Selenocysteine Biosynthesis

The video explains the process of protein synthesis, how information from DNA is used to build complex protein molecules from simpler amino acids, and how the order of bases controls the order in which amino acids are assembled,...

Peptidyl Transferase/Ribosome Physiology, Biochemistry, and Mechanism

The novel coronavirus’s genetic sequence has a segment that produces a substance known as nonstructural protein 1.

What's the maker movement all about? FabLab creator Neil Gershenfeld of MIT talks about its impact and potential for the future, and tips his hat to the White House Maker Faire.

This lesson explains what tetracyclines are, their mechanism of action and what bacteria and diseases are treated with tetracyclines. In this video we also talk about some contraindications of tetracycline use such as tetracycline...

Shine-Dalgarno/Kozak Sequences & 70S Ribosome Assembly

Cell Structure and Function Set: 5. This clip focuses on the structure and function of the centrosomes as well as the rough and smooth endoplasm reticula.

Biology can be pretty dry. You’re stuck in a classroom studying a textbook full of boring definitions and complicated diagrams... That’s why we’re going on a field trip with Sally! She’s visiting a floating city in the Pacific Ocean –...

Join Sally as she tours the heart of Zoo York, the city that never sleeps. She stays awake with coffee and Zoober Eats! This lesson will continue to delve into the structure of animal cells, focusing on components that synthesise and...

Genetic Expression Set: 3. This clip examines the chemical structure of DNA and RNA and explains how the genetic code is written and expressed.

Genetic Expression Set: 5. This clip offers a simple look at the translation of M-RNA into protein. Some of the biological roles of proteins are presented as well.

Ok, so everyone knows that DNA is the genetic code, but what does that mean? How can some little molecule be a code that makes a single cell develop into a giraffe, or a monkey, or Tony Danza? Within this clip lie the answers, child!

Genetic Expression Set: 6. This clip provides a detailed look at the translation of M RNA into protein.

mRNA Processing: The 5'-7-methylguanosine Cap

Cell Structure and Function Set: 2. This clip introduces the structure and function of the components of the nucleus.

Proteins are made of a long chain of amino acids, which has been coded for by DNA. The order of the bases of DNA determines which protein is made, by coding for a specific order of amino acids. This is protein synthesis, and in this...

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...

Students will learn about the discovery of cells, the development of the cell theory, and the differences between animal cells and plant cells, Animations illustrate the different parts of a cell. Other terminology includes: organelles,...

Genetic Expression Set: 1. This clip introduces the process of gene expression, whereby information stored in the DNA of a gene is transcribed into messenger RNA and translated into a protein gene product.

Cell Structure and Function Set: 10. This clip looks at the structure of ribosomes and examines how they facilitate protein synthesis during the translation of M-RNA.

They are the core components of the brain, the vertebrate spinal cord, the invertebrate ventral nerve cord, and the peripheral nerves
