Term
| What are transposable elements? What are the two types of transposable elements? |
|
Definition
Transposable elements are sections of DNA with no known purpose that can replicate within the genome.
1. Transposons move through genome by DNA intermediate through "cut + paste" and "copy + paste".
2. Retrotransposons move through genome by RNA intermediate through "copy + paste" only. Most are this type.

Term
| Describe the process of retrotranscriptase movement. |
|
Definition
| First, the DNA is transcribed into RNA then translated to the protein reverse transcriptase. This creates a DNA strand from the RNA is was translated from. It then makes a second, complimentary strand from the first DNA strand. The DNA is then reinserted into the genome. |
