This journal entry is due on Friday, September 6, at midnight PDT. (Thursday night/Friday morning)
Contents |
- Store your journal entry in the shared Class Journal Week 2 page. If this page does not exist yet, go ahead and create it (congratulations on getting in first :) )
- Link to your journal entry from your user page.
- Link back from the journal entry to your user page.
- NOTE: you can easily fulfill the links part of these instructions by adding them to your template and using the template on your user page.
- Sign your portion of the journal with the standard wiki signature shortcut (
~~~~). - Add the "Journal Entry" and "Shared" categories to the end of the wiki page (if someone has not already done so).
Read
- Monkey book, pp. 47-82.
- Nirenberg, M. (2004) Deciphering the Genetic Code—a Personal Account Trends in Biochemical Sciences 29: 46-54.
- Moody, G. (2004) Digital Code of Life, Chapter 1, Hoboken, New Jersey: John Wiley & Sons, pp. 1-9.
- Hayes, B. (2004) Ode to the Code, American Scientist 92: 494-498.
Reflect
Readings
- What is the biggest discovery that I made from these readings?
- What part of the readings did I understand the least?
- How was the genetic code solved experimentally?
- What is the relationship between the genetic code and a computer code?
Where’s Your Stuff?
- How easily can you find “your stuff” on your computer?
- When you double-click on icons on your computer, how do you know that icon is a program, a website, or a file?
- Have you double-clicked on a file to have an unexpected program come up? And if so, have you been able to figure out how to open that file in the right program?
Individual Journal Assignment
- Store this journal entry as "username Week 2" (i.e., this is the text to place between the square brackets when you link to this page).
- Link from your user page to this Assignment page.
- Link to your journal entry from your user page.
- Link back from your journal entry to your user page.
- Don't forget to add the "Journal Entry" category to the end of your wiki page.
- Note: you can easily fulfill all of these links by adding them to your template and then using your template on your journal entry.
The Genetic Code
- Write out the complementary strand of DNA below the strand shown and be sure to label the 5’ and 3’ ends of the complementary strand.
5’-cgtatgctaataccatgttccgcgtataacccagccgccagttccgctggcggcatttta-3’
- There are six possible reading frames in double-stranded DNA. Using the genetic code, translate all possible reading frames of this DNA sequence, keeping in mind the following rules.
- In RNA, the T becomes a U, so everywhere you see a T in the sequence, read it as a U.
- The genetic code is read in the 5’ to 3’ direction.
- Use the single-letter abbreviations for the amino acids because that is what is commonly used by computer programs.
- Wiki Hint: if you start your line with a single space character, it will appear in the grey box surrounded by the dashed line as shown above.
Where’s Your Stuff?
- Open a text editor (Notepad on Windows, TextEdit on Macs, gedit on Linux, to name a few) and create a file that contains the following text, verbatim (copy-paste suggested):
<!doctype html>
<html>
<head>
<meta charset="UTF-8" />
<title>Hello</title>
</head>
<body>
<h1>Hello File!</h1>
<p>This is a text file that contains HTML.</p>
</body>
</html>
- Save this file as a text file (.txt extension). If you see any options or controls pertaining to “rich text” or “HTML,” make sure to disable them. Double-click on your newly-saved file; the text editor should have opened it.
- Change this file’s extension to .html — remember that the computer may protest, since it is trying to protect novice users from making a mistake. Insist that you know what you’re doing. Take note of the icon after renaming the file — did it change?
- Double-click on the renamed file; a web browser should open it now, and instead of code, you should see a very simple web page.
- Write a short report on how this exercise went for you in your individual journal page.
- Answer the “after” reflection questions above.
