Forensic Lab Data
1.
Insert a copy of your group’s agarose gel picture below.
2.
Measure the distance (in cm) from the front edge of the well to the farthest edge
of each band in each lane and enter the data in
Table 3
below.
3.
Using the size data you entered in Table 3, sort your bands into the STR genetic
loci in
Table 4
. If you have only one band in that size range, it means that
individual was homozygous for that allele at that locus. If you have two bands in
a size range, the individual is heterozygous for that locus with the associated
sized alleles. If you have no bands, it likely means your DNA sample or the
enzyme mix was compromised.
4.
Examine the data in
Table 4
. Based on the data, can you eliminate any
classmates from being a suspect? Which lane is the most likely perpetrator?
Why?
