Summative Assessment
Element 1
Element 1: Essay and Article (50%)
Students will submit a 1,500 word essay comparing a key process of prokaryotic to eukaryotic cell biology. In addition, students should also produce a 500 word article summarising a key area relating to the essay title for a non-specialist audience. The submission of the Essay and Article should occur as a single Microsoft Word document.
Essay Title: Genes & Genomes in Prokaryotes & Eukaryotes
Deadline: 4th February 2013
Assessment 1:
Learning Outcomes
The essay comparing a key process of prokaryotic to eukaryotic cell biology will assess a student’s ability to demonstrate their knowledge of key cellular processes (LO1), advances in the theoretical and practical aspects of the discipline (LO6), evolution of these systems (LO3) and their ability to utilise the scientific literature (LO4). Both the essay and the article will be assessed on the student’s ability to produce an informed debate and communicate to a specialist and non-specialist audience
(LO5 & 8). (Learning Outcomes Assessed 1, 3, 4, 5 & 6, 8).
Article Guidelines
Write a 500 word article summarising a specific area relating to the Genes & Genomes in Prokaryotes & Eukaryotes. The article does not have to focus on the topics covered in your essay, but does need to focus on a topic or issue which would be of interest to the general public.
The article should be written in a style appropriate for a broadsheet newspaper (e.g. The Guardian or the Times), and hence a level at which a well educated person could understand. However, the article should be directed to lay individuals (i.e. individuals with no high level knowledge in a
scientific discipline) and therefore should endeavour to explain concepts fully and not be over reliant on technical terms. Consider using points of interest, such as the identity of the researchers, the locations the work is taking place and direct quotations, to engage the reader. You should
ensure the article is accompanied by a title which will be appealing and eye catching for the general public. Citations and references are not required, since the article is not a piece of academic writing.
Essay Structure
The essay must be written in clear and concise English, normally in the past tense, and should comprise:Title. The title should include topical keywords and allude to the interesting conclusions of the essay. A title that emphasizes the main conclusions, or poses a question, has more impact than one that just describes the nature of the study.
Summary. The essay must include a summary (abstract) of not more than 250 words. The summary must be clear and comprehensible in its own right. References should not be cited, and any abbreviations used must be defined. The summary should if possible introduce the subject in the first sentence and present the main conclusion in the last sentence: when someone is skimming
a block of text, the first and last sentences receive the most attention.
Introduction. You should provide a brief background to place your essay in the broader context of
microbiology as a whole. You should also provide an indication of the scope of the topics which will
be covered and the significance of these to the public.
Main Body of Text. The text should be divided into appropriate subheadings (unnumbered; the
term Main Body of Text should not be included as one of the subheadings)
Discussion. Should not be too long. Excessive discussion of few facts often gives an impression
of poor science. The discussion should provide a summary of the key findings. It may be helpful to
list the main conclusions at the end.
References. These should be academic books journal articles and reviews. Typically between 10-
15 references should be used.
Journal Articles & Reviews
It is a good idea to take a look at some of the journal articles & reviews published
in your discipline This will give you a feel for
• Writing style
• Referencing & Citation
• Presentation standards
• Layout
• Sections
• Figures/Tables
• Note you are mimicking the process not copying the content
Presentation of Tables & Figures
• In essays and literature based assignments tables and figures should not be exact reproductions of those which have already been published in the literature. You should attempt to compile tables and figures which draw on information present in multiple sources. As such figures should be selfgenerated using programmes such as Microsoft Powerpoint and imported into the Word document prior to submission.
• Tables and figures should be broadly comprehensible without reference to
the text. Both should be accompanied by a title and a legend if necessary. It is
not necessary to repeat detailed descriptions of methods. Table titles should
precede the table. The figure title should be placed below the figure.
• In tables the symbols * † ‡ § ¶ # should be used for footnotes, rather than
superscript letters or numbers. When results are expressed as percentages, the
absolute value(s) corresponding to 100% must be stated. Figures should be
referred to in text as Fig. 1(a) not FIG 1A, Figure 1(A), etc.; or as (Fig. 1a) not
(Figure 1A). Multipart figures should be labelled (a), (b), etc., not A, (A) or B,
(B)..
You are restricted to the use of one tableand one figure in the essayTables should be broadly comprehensible without reference to the textFigures should be broadly comprehensible without reference to the textUsing Direct Quotes• It is permissible to use direct quotes• Direct quotes must be placed in quotation marks
• A citation and reference in the References must be provided.• Direct quotes should not be used unnecessarily or over used– Over use of quotes shows you can identify key points but are not able to synthesise this information into a coherent
argument

episodes of a suspense thriller that could be titled Our Wits
Versus Their Genes” (Lederberg, 2000).• Lederberg, J. (2000) Infectious history. Science 288, 287-293Length PenaltiesWritten submissions should not exceed the maximum word limit (including the figure and table legends and any appendices, but not the summary or references) and/or more than the maximum
number of figures and tables. For submissions which exceed these limits, 5% will be deducted
for each breach of the conditions outlined below to reflect the monetary penalties placed on authors by scientific journals. The penalty will be 5% per 500 words or part thereof over maximum and 5% per figure or table over the maximum (You are restricted to the use of one table and one figure in the essay).Penalties apply to both the essay and article i.e. an essay of 1501 words and an article of 501 words will have 10% deducted
Scientific Essay GuidelinesReferences. These should be academic books journal articles and reviews. Typically between 10-15 references should be used. All sources of information must be referenced and cited according to the
School of Science & Engineering guidance provided in the appendix of the module handbook or at the following site
http://lis.tees.ac.uk/referencing/sse_new.pdf.
Biological Species Names. These should be italicised and presented in
full at first mention (i.e. Escherichia coli) and abbreviated according to
scientific convention (i.e. E. coli; see Module Handbook Appendix for
further details).Abbreviations, Units & other details: Abbreviations should be defined at
first mention in both the summary and main text (see Module Handbook
Appendix for further details).Recommended & Preferred sources:Use web sites sparingly and generally focus on publically funded organisations.Do not use or cite lecture notes. Find an alternativeJournalsAnnual Reviews of
