Alu insert PV92Background:
– This
experiment examines PV92, a human-specific Alu insertion on chromosome
16.
– The
PV92 genetic system has only two alleles indicating the presence (+) or absence
(-) of the Alu on each of the paired chromosomes.
– This
results in three PV92 genotypes (++, +-, or --).
– The
+ and – “alleles” can be separated by size using gel electrophoresis.
•
The
Alu insert is 300 bp in length; + allele
is 715 bp in length; - allele is 415 bp in length
Question: Do I have the Alu insert PV92 on my 16th
chromosome; determined through polymerase chain reaction and gel
electrophoresis?
•
Hypothesis:. HINT, ‘kinda’ spelled out
in the test!
•
Test: We will isolate DNA from human
cheek cells. We will then amplify a segment of chromosome 16 using PCR. DNA
samples will be separated by different sized fragments using gel
electrophoresis. Finally, using proper staining methods to make the DNA visible
using Ethidium Bromide; we will be able to determine the genotype for the human
Alu insert PV92.It will be +,+ (yes, Alu); -,- (no alu), or + ,-(one alu).

You will NOT need to include full materials
lists, procedures or diagrams for this lab.
Each of these section headings should be included and
followed by “See Gene Connection hand outs.”
Data is a Labeled diagram of your DNA photo results after
gel electrophoresis and your observation journal. *Observation Journal is Key here!
Analysis will include a discussion of Possible types
of error and how they could have affected your results.
•
Conclusion as per rubric in paragraph
format.
