Answer key for the DNA Forensics and Color Pigments Activity Worksheet, covering topics like DNA separation, restriction enzymes, and gel electrophoresis.

1. What happens to the DNA fragments and Color Pigments activity? They separate into a color as they travel up the paper.
2. Which samples have a similar makeup? Will depend on the food coloring.
3. Which sample appear disimilar? Will depend on the food coloring.
4. How can you apply your observations to restriction mapping? Food coloring solutions separate into components. Similar components will map similarly to restriction fragments in DNA fingerprinting.

Questions on restriction enzymes:
1. What does it mean when we say that Restriction Enzymes are "sequence specific"? They cut DNA when they encounter a specific sequence along the DNA.
2. What is the purpose for the ligase? To bind two DNA fragments.
3. How does electrophoresis separate the DNA fragments? It separates them based on the length of the DNA fragments.
4. What is the difference between larger and smaller fragments and their migration distance? Larger fragments travel slower while shorter fragments travel faster.
