Students have the opportunity to interpret actual case results from the use of the Restriction Fragment Length Polymorphism (RFLP) method to characterize human DNA samples as applied in paternity analysis and sex crimes investigations.

Students practice a problem using DNA profile analysis to characterize human DNA samples as applied in paternity analysis and sex crimes investigations.

Family studies are a good way to learn about DNA profiling and RFLP analysis because students can follow the inheritance of DNA markers from one generation to the next. Students have the opportunity to do this in this activity.

In this activity, students learn the concepts and techniques behind DNA profiling of the national DNA databank. Students will then have the opportunity to collect and interpret actual STR data, and to answer one or more questions.

Read about the findings from the scientific group from the National Center for Human Genome Research, which published a modification to traditional karyotyping that permits rapid identification of chromosomal alterations.

Read this illustrated tutorial about the relationship between the HIV virus and AIDS. Also contains treatment and diagnosis information.

This problem set introduces students to basic concepts about the immune system. Correct answers are reinforced with a brief explanation, and incorrect answers are linked to tutorials to help solve the problem.

Three immunology case studies for students to collaboratively diagnose using the information learned in the accompanying tutorials.

In this activity you will learn the concepts and techniques that are part of the DNA profiles.Dictionary - View detailed dictionary
