This activity will allow students to evaluate two patients with possible neurological symptoms. Students will come up with possible diagnosis and determine how to test for these diagnoses. A patient and his wife come in to see you with a concern.

The patient has a history of sickle cell disease in his family, but neither of his parents have exhibited any symptoms. The wife is an immigrant from rural tropical Africa and has no idea if her family has any history of sickle cell disease.

However the area she is from has a high incidence of sickle cell anemia in the population. The couple has 2 children, ages 4, 8 and would like to have another. The couple has come to you for advice on whether or not to have another child, and what to tell their children about the family medical history.

How is DNA analyzed and manipulated using restriction enzymes? Students compare the DNA fragments with the known restriction map of bacteria phage lambda. This activity demonstrates how DNA sequences can be mapped and characterized, such as in the Human Genome Project and how DNA is cut and arranged during genetic engineering.

What is genetic engineering, and how is this technique used? Students perform a genetic engineering experiment using bacterial transformation to introduce fluorescent genes into Escherichia coli E.

This activity helps students understand what genes do and how they can be manipulated by genetic engineering. This activity will confirm that different genes introduced by transformation will result in different visible characteristics.

This activity helps students to visualize regulation and relate this regulation to the lac operon system. Highly recommended for AP Biology.

This activity allows the gene regulation concept to be presented in a more inquiry fashion. Students will transform E. They will hypothesis why the cells did not glow and use PCR B to test their hypothesis. After the PCR the students will learn the regulation of this gene, and will induce the promoter to express the product.

In this lab investigation students will learn about a technique called polymerase chain reaction PCR that allows us to examine a very small piece of DNA.

This gene codes for the GFP protein, an protein normally produced by jellyfish that is transformed into bacteria in a plasmid pGLO. This activity lends itself to be conducted inquiry style.Dear Twitpic Community - thank you for all the wonderful photos you have taken over the years.

We have now placed Twitpic in an archived state. Jun 20,  · Fingerprint evidence left behind by a suspect or victim may identify who was at a crime scene and what he or she touched.

However, it is important for defense attorneys to know, and to inform the jury, that the techniques used to locate and identify fingerprints are far from a perfect science.

Test Directory A venipuncture performed using a vacutainer Venipuncture is useful as it is a minimally invasive way to obtain cells and extracellular fluid plasma from the body for analysis. Blood flows throughout the body, acting as a medium which provides oxygen and nutrients to tissues and carries waste products back to the excretory systems for disposal.
