Finding the Lost Children 3/21/13 Key Question: How can DNA
fingerprinting help find the lost children? Initial Thoughts:
Slide 3
Evidence Procedure 1. Figure 1 shows the DNA fingerprints of a
child, his or her biological parents, and an unrelated child.
Examine and compare the DNA fingerprints. Record your observations
in your science notebook.
Slide 4
Evidence 2. To try to identify their missing children, Mai,
Paul, Belinda, and John each give blood and have their DNA
fingerprints made. They obtain a court order to test the blood of
the children in Samarra. Cut out the Childrens DNA fingerprints and
compare them one by one to the parents DNA fingerprints, shown in
Figure 2 below. Be sure to include the label with the fingerprint
(for example, Girl 1).
Slide 5
Evidence 3. Record your observations and conclusions in your
science notebook.
Slide 6
Analysis Questions 1.Use DNA fingerprint evidence and the blood
type evidence to explain the following. a.Which child or children
are not likely to be those of Belinda and John? b.Which child or
children are likely to be those of Belinda and John? c.Which child
or children are not likely to be those of Mai and Paul? d.Which
child or children are likely to be those of Mai and Paul?
Slide 7
Analysis Questions 2.Write a convincing statement about which
of the eight children (if any) are the children of Belinda and
John, and which of the children (if any) are the children of Mai
and Paul. In your statement, provide as much evidence as you can to
convince a judge that the biological children of these parents have
been found. Be sure to include evidence from previous
activities.
Slide 8
Summary At first what did you think about how DNA
fingerprinting can help find the lost children? What did you learn
about using DNA fingerprinting to find the lost children? (Minimum
of 3 sentences!!!) What are some further thoughts or questions you
have about how DNA fingerprinting can help find the lost
children?
Slide 9
Reflection What are the pros and cons of the government
requiring parents to fingerprint their children when they are
young?
