Introduction
The University of North Texas has sent four of their brightest Cell Biology students to
Scotland to do research with the University of Glasgow on an unknown tissue sample
they obtained while retrieving equipment being used to witness the Lock-Ness Monster.
The tissue sample is the only evidence that has been obtained while trying to determine
the likelihood of this creature’s existence. With the use of breakthrough technology and
highly skilled laboratory techniques, these students will develop a cladogram to show
the cladistic relationship between several known species.
Experimental Objective (purpose and hypothesis
The purpose of running these samples through Proteome testing will help determine if
this sample is a never before see organism and if it is genetically related to any of the
other known tested organism samples. This hypothesis is solely based on the fact that
this Loc-Ness Monster sample was taken from the water, the closest ancestor that we
will be testing with be the water dwelling Catfish because all of the sightings have been
on the water.
Experimental Approach (methods of how
The tissue sample obtained will be used to construct a cladogram of 5 tissues samples
from 4 known origins by sorting protein molecular weights of the tissue proteins. By
using SDS-PAGE (Sodium dodecyl sulfate – polyacrylamide gel electrophoresis) a form
of electrophoresis that treats samples with SDS to denature proteins.
SDS-PAGE separates according to their mobility, the samples can have similar charge
to mass ratios results in fractionation by size. The importance of the sodium dodecyl
sulfate (SDS) is that it binds to and coats the protein while keeping the protein in a
denatured state linearly. This form allows proteins to migrate in the gel as if the protein
has an equivalent negative charge, with mass of the protein that affects the migration
rate through the gel.
