+ Make a single base pair substitution mutation in the gene below that results in a protein that is longer than the protein produced by the original gene. When you are satisfied with your change and its effect, click the SUBMIT button.
+ Note that a "single base pair substitution mutation" is when a single base is changed to another base; for example, changing the A at position 80 to a T. Deletions and insertions are not allowed.

In this code:
* **width** and **height** specify the dimensions of the application, in pixels.
* **genex_dna_sequence** is the default DNA sequence that appears when the problem opens.
* **dna_sequence** contains the application's state and the student's answer. This value must be the same as **genex_dna_sequence**.
-* **genex_problem_number** determines what the user has to find to answer the problem correctly. It is hard-coded in the Java GWT code that is used to produce the JS. Its value can range from 1 to 5 and corresponds to the 5 'Edit a Gene' problems encountered in 7.00x.

-.. warning:: Jean-Michel: I'm not sure what to say about **genex_problem_number, since this info is just for 7.00x. Would something like this work?
-
- **genex_problem_number** specifies the number of the problem. This number is based on the five gene editor problems in the MITx 7.00x course--for example, if you want this problem to look like the second gene editor problem in the 7.00x course, you would set the **genex_problem_number** value to 2. The number must be 1, 2, 3, 4, or 5.

- (This seems a little odd--do all courses have to use the same five gene editor problems?)

Molecule Editor
************************
-.. warning:: Jean-Michel: I started creating documentation for this a couple of weeks ago, based on the molecule editor in the demo course. In addition to the problem XML that you provided, that problem included some HTML text as well. Can you look over it and let me know if you think it's OK to keep that in? (To be honest, the two collapsible sections in the HTML component look kind of ugly in the LMS, so I'm happy to hear any suggestions for them.)

+Students can use the molecule editor to learn how to create molecules. The molecule editor allows students to draw molecules that follow the rules for covalent bond formation and formal charge, even if the molecules are chemically impossible, are unstable, or do not exist in living systems. The molecule editor warns students if they try to submit a structure that is chemically impossible.
The molecule editor incorporates two tools: the JSME molecule editor created by Peter Erl and Bruno Bienfait, and JSmol, a JavaScript-based molecular viewer from Jmol. (You don't need to download either of these tools--Studio uses them automatically.) For more information about the JSME molecule editor, see `JSME Molecule Editor
