6.5 Conformational changes upon protein–DNA interactions
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

6.2 Catalytic mechanisms
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.

The Autistic Neuron
This self-described “basic neuroscientist” confesses he never thought he’d give a talk on autism, but as Mark Bear recounts, decades of research in the basics are now paying off with important insights into the etiology and treatment of brain disorders, including autism.

Village Works
From 1992 to 1993, women in villages of rural north west China were given cameras to record a year of their daily life, as pat of a women's reproductive health programme supported by the Ford Foundation. The resulting pictures not only formed an exhibition, but were used as prompts to discussions with officials on improving conditions in the areas involved.

1.8.3 Explaining the observations

Having made and reviewed our observations, we are now in a position to interpret them – why are the rocks the way they are? The sedimentary strata that we see in Figure 16 were likely to have been deposited in essentially horizontal layers, so why is one set tilted and the other horizontal? To answer

Digital ?serial vision? - new approach in urban composition teaching
The paper discusses the following problem: How can digital technology are integrated with urban composition teaching to provide a better understanding of the aesthetical and emotional aspects of the city? It argues for the current need for an integration of computer modelling and the approaches developed form the work of K. Lynch, G. Cullen, R. Krier, F. Ching. The paper is based on the experience in design studio teaching and an experiment completed with students. The exercise shows the student

Introduction

This unit will introduce you to the law making process in Scotland. It is drawn from the Open University course W150 An introduction to law in contemporary Scotland. The Scottish legal system and many aspects of the law in Scotland are different from those in England and Wales. Like the law of England and Wales, Scots law today represents centuries of development and growth. Its evolution has been influenced by many factors, social and economic, the effects of war and religious change,

Introduction

This unit considers the way that judges make law, how the common law system works and the advantages and disadvantages of a system like the British one that relies heavily on such rules and rule making. The unit will set out the basic differences between ‘civil code’ systems and ‘common law’ systems, and consider the relationship between judge-made law and statutory law.

Fourier series
This unit is concerned with the technique of expressing a periodic function as a sum of terms, where each term is a constant, a sine function or a cosine function. There is a strong analogy with the technique of expressing a (non-periodic) function as a Taylor series, which is a sum of terms that are powers of the independent variable(s); in both cases, working with just the first few terms generally gives a useful approximation. This unit assumes the following background knowledge: the definit

Learning outcomes
Childcare, education, working conditions, healthcare, crime … these issues are hotly debated in today's society. They are also issues that Robert Owen, seen by some as a visionary and by others as a knave and a charlatan, sought to address in the early 1800s. This unit uses a series of essays written by Owen to explore the ideas of this important and controversial figure.
