When you click Submit (at the bottom of this web page) it will save your work on the server for me. If you get a "proxy error" hit -refresh- until you get a "Thanks"

You can't resume a submission, so, you might want to actually write your answers in Word (so you can spell check them) and then cut-and-paste into the boxes. That way, if the computer misplaces your work you can just re-paste the answers, and if you don't finish in one "sitting" you don't have re-do all the work.

You don't have to answer all the questions or read all the articles. The more you do, the more credit you get.

TAB OR USE THE MOUSE Between the fields....

Answer the questions as best you can. The boxes will expand as you type if you need more space. (Don't worry if it is a one word answer. The box size is standard.)

The "form handler" software doesn't like "blanks" so, if you don't have an answer, leave the -No answer- in the box.

the body?


Q03-Using the diagram on Page 23, titled “Copy or cut,” what are the two types of transposons and how
does each type move?


Q04-What is the transposon that scientists know is still “hopping” around the human genome? What
are some potentially negative and positive effects of this activity?


Q05-What happens to make a live transposon a “transposon fossil”? What are a few positive outcomes
that have come from “transposon fossils”?
