Data/Drawing
Using a blank piece of paper, sketch and color your alien, making sure to include all relevant (known) traits. Be sure to include
your alien’s genus and species at the top of your drawing and data sheet. Place your name on your drawing. (NOTE: The
genus name must be capitalized and the species name always starts with a lower case letter.)
Analysis
Answer the following questions on the back of your alien picture:
1. Give the tRNA sequences for Gene D.
2. How does a single change in a nitrogen base alter the formation of a resulting protein?
3. If you knew a particular amino acid sequence, could you figure out the DNA for that sequence? Why or why not?
4. What is the difference between transcription and translation?
