7.3 The eukaryotic chromosome (continued)
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
Acknowledgements
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.

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.

This unit explains the function of the cytoskeleton and its role in controlling transport of vesicles between different subcellular compartments.
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.

1.1 So what's it all about? iSpot is a website aimed at helping anyone identify anything in nature. Once you've registered, you can add an observation to the website and suggest an identification yourself or see if anyone else can identify it for you. You can also help others by adding an identification to an existing observation, which you may like to do as your knowledge grows. Your reputation on the site will grow as people agree with you identifications. You may also like to visit our forums which offer lively debat
Supporting community archaeology in the UK
The "Supporting Community Archaeology in the UK" website produced by for The Council for British Archaeology (CBA) publishes an updated report (in PDF format) by Dr Suzie Thomas entitled "Community Archaeology in the UK: Recent Findings". The report concludes that in 2010 up to 215,000 individuals may be available to be involved in such projects, a resource to be assessed against the declining role of universities in excavations due to funding cuts.Professional archaeologists are usually in char
Dim sum
Dim Sum is an English language websites that covers cultural and news stories of interest to Chinese communities around the United Kingdom. From the main page, users can view sections covering issues such as: family; community; food; performance arts; lifestyle; identity; immigration; and gender. The resource can be browsed by section, or by individual issue. For example, the features' section on women covers such varying topics as: women writers; being a single Chinese woman; Western impression
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. From the main page of the website, users can view a textual introduction to the project, and link to selected photographs, covering: work; f
Impact of a global temperature rise of 4C
This website has been developed by the UK government as a result of the UN Climate Change Negotiations in Copenhagen (COP15). It presents a series of scenarios for the risks and results of a 4C climatic temperature rise worldwide, focussing on several key areas. From the agricultural perspective, climate change impacts on crops, water availability and forest fires are presented. Together with evidence of increased risks of cyclonic and drought conditions, this series of maps presents an uncomfor
South African Journal of Bioethics and Law
The South African Journal of Bioethics & Law is a twice yearly, peer reviewed, open access journal which began publication in 2008. Its' scope includes bioethics, health law, research regulation, health policy, and human rights in clinical practice. Tables of contents are listed for each issue with links to an abstract and full text of each article. There is also a search function for articles, which can additionally be browsed by author and title.
Gesnerus : Swiss Journal of the History of Medicine and Sciences
Gesnerus is the official journal of the Swiss Society for the History of Medicine and Natural Sciences. It publishes original articles, short communications and documents on different periods and aspects of the history of medicine and sciences and also focuses on theoretical and social aspects of this subject. Journals from 2006 to the present only have summaries of articles, otherwise it is full text. The Web site features an index volume and advanced search function. The publication is produce

Aging and Society was established as section of the German Soociological Association in 2000. It is a "forum for addressing the issues of the relationship of aging and social development and the social conditions of aging". There is information on the wrokshops and meetings the section organizes and access to meeting reports, as well as a news and event section.
Combined Harare Residents Association
This site is maintained by the residents association of Harare Zimbabwe. Although intended to give local residents a chance to voice their opinions and organise grass roots events, researchers may find it of value in providing an insight into living conditions in modern day Zimbabwe. It also includes some news, email discussion forums and comment on the political and land ownership policies of the government under Robert Mugabe. NB. The website has not been updated since 2009.

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,
