Individual Journal Assignment
- Store this journal entry as "username Week 11" (i.e., this is the text to place between the square brackets when you link to this page).
- Create the following set of links. These links should all be in your personal template; then use the template on your journal entry.
- Link to your journal entry from your user page.
- Link back from your journal entry to your user page.
- Link to this assignment from your journal entry.
- Don't forget to add the "BIOL368/F11" category to the end of your wiki page.
Preparation for Journal Club 3
In preparation for the Journal Club, each individual will do the following assignment on their individual Week 11 Journal page.
- Make a list of at least 10 biological terms for which you did not know the definitions when you first read the article. Define each of the terms. You can use the glossary in any molecular biology, cell biology, or genetics text book as a source for definitions, or you can use one of many available online biological dictionaries. List the citation(s) for the dictionary(s) you use; a proper citation of a web site includes the URL and the date accessed.
- Write an outline of the article. The length should be the equivalent of 2 pages of standard 8 1/2 by 11 inch paper. Your outline can be in any form you choose, but you should utilize the wiki syntax of headers and either numbered or bulleted lists to create it. The text of the outline does not have to be complete sentences, but it should answer the questions listed below and have enough information so that others can follow it. However, your outline should be in YOUR OWN WORDS, not copied straight from the article.
- What is the main result presented in this paper? (Hint: look at the last sentence of the introduction and restate it in plain English.)
- What is the importance or significance of this work?
- What were the limitations in previous studies that led them to perform this work?
- What were the methods used in the study?
- What samples did they collect and use for the microarray experiment?
- How many microarray chips did they hybridize in the experiment?
- Which samples were paired to hybridize on the chip?
- Which was labeled red (Cy5)? Which was labeled green (Cy3)?
- How many replicates did they perform of each type?
- Biological replicates are made from entirely different biological samples.
- Technical replicates are made when one biological sample is split at a particular stage in the procedure and then carried through to the end of the procedure.
- What do they say about how they performed each of the steps listed in the Overview of Microarray Data Analysis section below?
- Briefly state the result shown in each of the figures and tables.
- How do the results of this study compare to the results of previous studies (See Discussion).
- Upload your completed PowerPoint slides to your journal page by the Week 11 journal deadline (you may make changes before your presentation Tuesday morning, but I will be evaluating the presenttion you upload.)
Shared Journal Assignment
- Store your journal entry in the shared BIOL368/F11:Class Journal Week 11 page. If this page does not exist yet, go ahead and create it.
- Link to the shared journal entry from your user page; this should be part of your template.
- Link the shared journal page to this assignment page.
- Sign your portion of the journal with the standard wiki signature shortcut (
- Add the "BIOL368/F11" category to the end of the wiki page (if someone has not already done so).
Often, research is classfied as either hypothesis-driven research or discovery-driven research (where research is conducted without having a prior hypothesis as to the results). For each of the papers that you have read for journal club this semester, answer the following:
- Classify each paper as hypothesis-driven or discovery-driven and explain why you gave it this designation.
- What do you see are the advantages and disadvantages to each kind of research?
