1. Open the link: http://learn.genetics.utah.edu/content/epigenetics/rats/
2. We will conduct 3 trials:
• Trial 1: One lick per day (~7 licks)
• Trial 2: Two licks per day (~14 licks)
• Trial 3: Five licks per day (~35 licks)
3. Count and record the number of histones that you see in the simulation screen/window for each trial in the table below.
4. Record the observed behavior for each trial in the table below.

1. What do you predict will be the effects of the mother rat licking her pups a lot or a little? State two hypotheses-- one regarding the structure of the GR gene and one regarding the pup’s
ability to manage stress.
2. How did you run your experiment? (Provide many details - someone should be able to replicate the experiment)
3. What did you find? (Only provide data - not your interpretation)
