Alu sequence is a short stretch of DNA originally characterized by the action of the Alu restriction endonuclease. Alu sequences of different kinds occur in large numbers in primate genomes. In fact, Alu sequences are the most abundant mobile elements in the human genome. They are derived from the small cytoplasmic 7SL RNA, a component of the signal recognition particle. The event, when a copy of ...

Articular cartilage, also called hyaline cartilage, is the smooth, glistening white tissue that covers the surface of all the diarthrodial joints in the human body. As its name implies, articular cartilage is critical in the movement of one bone against another. Articular cartilage has an incredibly low coefficient of friction which, coupled with its ability to bear very large compressive loads, m...

Beta cells (beta-cells, β-cells) are a type of cell in the pancreas in areas called the islets of Langerhans. They make up 65-80% of the cells in the islets. In mammals, insulin is synthesized in the pancreas within the beta cells (β-cells) of the islets of Langerhans. One to three million islets of Langerhans (pancreatic islets) form the endocrine part of the pancreas, which is primarily an ex...

Video Lectures - Lecture 2/nTopics covered: /nBiochemistry 1/nInstructor: /nProf. Robert A. Weinberg/nTranscript - Lecture 2/nOK. So today we're going to spend a little bit of time on some elementary chemistry just to develop our language that we use with one another. And so when I say hydrogen bond, you don't stare blankly at me and scratch your heads. Many of you have had this already. For man...

Video Lectures - Lecture 5/nTopics covered: /nBiochemistry 4/nInstructor: /nProf. Robert A. Weinberg/nTranscript - Lecture 5/nGood morning, class./nI just wanted to spend the first couple minutes clearing up three issues. None is a major conceptual issue, but we like to focus on details and get them right, get them correct here as well. Firstly, I misdrew a reaction last time that described why ...
