Introduction
Genomes are composed of DNA, and a knowledge of the structure of DNA is essential to understand how it can function as hereditary material. DNA is remarkable, breathtakingly simple in its structure yet capable of directing all the living processes in a cell, the production of new cells and the development of a fertilized egg to an individual adult. DNA has three key properties: it is relatively stable; its structure suggests an obvious way in which the molecule can be duplicated, or replicated;

2.2 Chaperones help polypeptides to fold
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.

2.4 Analysis of nucleic acids by electrophoresis and hybridisation
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

AlgTop9: Applications of Euler's formula and graphs
We use Euler's formula to show that there are at most 5 Platonic, or regular, solids. We discuss other types of polyhedra, including deltahedra (made of equilateral triangles) and Schafli's generalizations to higher dimensions. In particular in 4 dimensions there is the 120-cell, the 600-cell and the 24-cell. Finally we state a version of Euler's formula valid for planar graphs. This is the ninth lecture in this beginner's course on Algebraic Topology, given by Assoc Prof N J Wildberger at UNSW

Formation of Acetyl Co-enzyme A
This page explains the formation of Acetyl Co-enzyme A which is key to the synthesis of many organic molecules in cells. An acetyl group is a simple two-carbon-atom molecule which is sufficiently reactive to make it possible to use as a building block for larger carbon skeletons. A large number of molecules that are synthesised in cells are built from two-carbon acetyl groups. An acetyl group derives from ethanoate (acetate) and is named acetyl when it forms a group within a larger molecule. I

Powering the Planet: The Challenge for Science in the 21st Century
The supply of secure, clean, sustainable energy is arguably the most important scientific and technical challenge facing humanity in the 21st century. Rising living standards of a growing world population will cause global energy consumption to increase dramatically over the next half century. Within our lifetimes, energy consumption will increase at least two-fold. This additional energy needed is not attainable from long discussed sources, the global appetite for energy is simply too much. Pet
