Aminoacyl tRNA Synthetase: Part 1

In this video, we explore the biosynthetic pathway for cocaine, as it occurs in the leaves of the Coca plant.

Taurine Biosynthesis

Selenocysteine Biosynthesis

This video discusses genetic variants. The video explains how DNA codes for proteins and how variations in the DNA sequence can lead to alterations in the amino acids and shape of the protein produced, which can lead to changes in the...

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

There are a number of substances that are vital to all living organisms. In this lecture, I talk about substances like carbohydrates, lipids, proteins and nucleic acids, going into some detail about their structures and importance.

The video discusses mutations in DNA and how they can affect the organism that carries them. It explains how mutations can occur in the coding and noncoding parts of DNA and how they can impact protein synthesis, specifically by changing...

Quinoa is considered a superfood, meaning it has very high nutritional value. Learn about the variety of vitamins, proteins, and other nutrients found in quinoa and the benefit they have for our bodies.<b<br/>r/>

Quinoa part 2/5

Proteins and Enzymes for Anatomy and Physiology

In this video, we explore the basic mechanisms of drug interactions (inhibition and induction), using examples with cytochrome P450 and two drugs, drug A and drug B.

A mutation is a random change in the DNA. Mutations can be neutral, which means it does not cause a change in a trait of the organism, or it could cause a beneficial or a harmful mutation. There are a few different types of mutations -...

It explains symbiotic association and fixation of nitrogen by free nitrogen fixers. It lists examples of bacteria and cynobacteria involved. It also describes events during nodule formation and activity of nitrogenase enzyme.

The video is about protein synthesis, including the stages of transcription and translation. The video also covers the structure of an RNA molecule and how it is involved in protein synthesis. It goes into detail on the two stages of...

Transfer RNA (tRNA), Codons, and Anticodons

The video discusses the structure of amino acids, their functional groups, and their importance as a major component of proteins. It explains how amide bonds are formed between carboxylic acid and amine groups, and how amino acids can...

Hey guys! This is my first video on amino acids! In this video I teach you guys how to memorize and remember all of the essential amino acids. In this video, I discuss all 9 (or 10 or 12) essential amino acids, describing why there...

Lesson on the urea cycle, how it functions, how it removes nitrogenous waste such as ammonia/ammonium and what regulates the urea cycle.



In this lesson you w

It's time to start learning about all the monomers that make up large biomolecules, and the first one we will look at is the amino acid. These make up proteins, which is most of what you are, so this is pretty important stuff!

Once known as a party drug, ketamine may help treat chronic depression. Hear from a top researcher how the drug can repair brain circuits and t he perils and promises of a new medicine.

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

Remember how the Ninja Turtles came to be? Yes you do. It was the ooze! A radioactive ooze that mutated their DNA in just the right way to give them the ability to walk upright, talk, and do ninjutsu. Now, I'm as a big a Turtle fan as...

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!
