Question
Chapter 35, Problem 15TYPSS
Summary Introduction
To review:
The designing of an experiment to test whether changes in the expression patterns of tool-kit genes enabled a dramatic diversification of vertebrates’ appendages and bodies, like arthropods.
Introduction:
The tool-kit genes are a small gene group, which are involved in the controlling and regulation of embryonic development of an organism. These genes are highly conserved among organisms of the same phylum. The differences in the expression of tool-kit genes lead to changes in body plan, change in patterns, identity, and the number of body structures. The Hox (short for homeobox) genes are examples of tool-kit genes.

10. Your instructor will give you 2 amino acids during the activity session (video 2-7.
A. First color all the polar and non-polar covalent bonds in the R groups of your 2 amino acids
using the same colors as in #7. Do not color the bonds in the backbone of each amino acid.
B. Next, color where all the hydrogen bonds, hydrophobic interactions and ionic bonds could
occur in the R group of each amino acid. Use the same colors as in #7. Do not color the bonds
in the backbone of each amino acid.
C. Position the two amino acids on the page below in an orientation where the two R groups
could bond together. Once you are satisfied, staple or tape the amino acids in place and label
the bond that you formed between the two R groups.

Find the dental formula and enter it in the following format:
I3/3 C1/1 P4/4 M2/3 = 42 (this is not the correct number, just the correct format)
Please be aware: the upper jaw is intact (all teeth are present). The bottom jaw/mandible is not intact. The front teeth should include 6 total rectangular teeth (3 on each side) and 2 total large triangular teeth (1 on each side).
