Lipids, Carbohydrates, and Nucleic Acids Practice Problem | MIT 7.01SC Fundamentals of Biology

PROFESSOR: Hi, my name is Nicole and welcome to recitation. Today we are going to go over the practice problem for the nucleic acids, carbohydrates, and lipids section of the biochemistry module. First, if you haven’t had a chance to look at this problem, please go back and look at it and then come back […]

Protein Synthesis in the Cellular Factory

If you could step inside one of your cells, you’d see something that looks a lot like a factory building thousands of different molecular machines. It would have tiny assembly lines starting in the cell’s nucleus and stretching out to structures called ribosomes. These assembly lines start with DNA and build RNAs and Proteins—-in a […]

What is Biochemistry? What do Biochemists study? | Biology |

What is Biochemistry? The Chemistry of Life. You know about atoms and molecules from Chemistry. But there’s nothing ALIVE about chemistry. It’s just chemicals in a beaker. So what’s so special about the molecules of life? It’s a case of emergent properties. That is, as biological molecules come together and interact, new and surprising properties […]

Ahern’s BB 350 at OSU – 19. Transcription & Translation

>>Happy Friday, everyone. Everybody wants to have extra credit today, I know. I know they do. Well, I have to be a little careful with this. I have a– there’s a fairly large group of students that have gone to a meeting, today who were very responsible and told me about this before the meeting. […]

Protein Sythesis

Welcome to Protein Synthesis. In this video, you’ll explore what protein synthesis is including the two parts of its process: transcription and translation. Protein synthesis means making protein. Whenever cells want to make any type of protein, they use a process that includes building blocks like amino acids, to build new proteins inside of the […]

What Is Protein Synthesis – How Are Proteins Made – Transcription And Translation

Protein synthesis. So, how are proteins built? In this video we are going to go through a very basic look at how this happens. There are two major events that happen during protein synthesis, transcription and translation. Transcription has three phases, initiation, elongation and termination. The initiation phase of transcription occurs in the nucleus of […]

Nucleosides, Nucleotides & Nucleic Acids

In his book, “What Mad Pursuit,” Francis Crick does an excellent job capturing the essence of what has been our focus in CHEM 332. The idea that without understanding molecules, we cannot understand life itself. We want to carry this theme forward in our final section on nucleic acids. Where we want to understand the […]

The Central Dogma of Biology

The DNA double helix contains two linear sequences of the letters A C G and T, which carry coded instructions. Transcription of DNA begins with a bundle of factors assembling at the start of a gene, to read off the information that will be needed to make a protein. The blue molecule is unzipping the […]

Molecular structure of RNA | Macromolecules | Biology | Khan Academy

– [Voiceover] We’ve already payed a lot of attention to the molecular structure of DNA. In fact right depicted in front of us, we have two strands of DNA forming a double helix, and we can look at the telltale signs that this is DNA. In particular, we can look at the five-carbon sugar on […]
