HIV Replication and Life Cycle
HIV replication is a complex multi-staged process that includes crucial steps taking place on the exterior as well as the interior of the target host cell. The first three steps involved in cell entry are termed attachment, co-receptor binding and fusion. Each step is crucial to successful viral reproduction. Once HIV virus penetrates the cell, it releases its RNA into the cell. Run time 02:29.

Virus Lysogenic Cycle
In a lysogenic cycle, viral nucleid acid becomes part of the host cell chromosome and it's replicated with it. Eventually the virus enters a lytic cycle and kills the host cell. 3-D animation takes you through the steps of the lysogenic cycle. Grades 7-12. 1:25 min.

Photosynthesis, Part 1
This is a short slidecast of the process of photosynthesis that starts with a defintion. A quote from the video: "The primary function of photosynthesis is to produce organic compounds useful to the cell. This is accomplished by using light, carbon dioxide, and water. Overall, photosynthesis converts light energy from the Sun to chemical energy."

Design of an eLearning System for Accreditation of Non-formal Learning
This paper deals with issues related to the non-formal learning in vocational education, and the role of ICT for providing appropriate accreditation model in such education. The presented conclusions are based on the Leonardo da Vinci project LeoSPAN. The paper emphasises on the development of a model and a prototype of an adaptive eLearning system that ensures the pre-defined learner outcomes. One of the advantages of the eLearning system is the flexibility for people who upgrade and improve th

3.1 Protein diversity

Of course, our bodies can't just be made up of squidgy bubbles of phospholipid, or we would collapse in a heap on the floor! Stiffer frameworks, both inside and outside the cells, also exist and help to define shape and add strength. These frameworks are formed largely from structural proteins, a class of polymeric materials that form fibres and filaments to provide mechanical support for cells and tissues. Structural proteins are made inside cells but are often then moved into the spa

2 Construction with lipids

The cell membrane is constructed from lipids. Chemically, lipids are a rather varied group of compounds that include all the substances you might already think of as fats or oils. What they have in common is that they are all insoluble in polar liquids like water, but soluble in organic (carbon-based) solvents: by this I mean the sort of smelly solvents you tend to find in paints, glues and degreasing agents; chloroform is one example. Lipids make up the fatty components of living organisms a

Nucleic acids and chromatin
This unit helps you understand the properties of nucleotides and how they contribute to secondary and tertiary structures of nucleic acids at the molecular level. You will learn about the different composition and roles of nucleic acids in the cell, their interactions with each other and the use of ribozymes, aptamers, antisense and hybridization as tools in molecular research. The unit covers the function of DNA packaging within the cell, the interactions between the DNA double helix and the nu

Globalization of Science: Opportunities for Competitive Advantage from Science in China, India and B
When Fiona Murray visited research centers in China recently, scientists greeted her quizzically: “People were baffled about what a business school professor was doing in stem cell and gene sequencing labs,” Murray says.

As it turns out, Murray’s tour was integral to her own MIT Sloan research exploring how

4.4 Predicting conformation from sequence
In this unit we explore how proteins are the 'doers' of the cell. They are huge in number and variety and diverse in structure and function, serving both the structural building blocks and the functional machinery of the cell. Just about every process in every cell requires specific proteins. The basic principles of protein structure and function which are reviewed in this unit are crucial to understanding how proteins perform their various roles.
