What is Cloning?

This is an introductory lesson on cloning.  It is a mini webquest that gives students an opportunity to learn about the different ways clones come about and then gives them the opportunity to participate in a somatic cell nuclear transfer in a virtual mouse.  Through this lesson, students will develop an understanding of cloning and the different techniques used to accomplish it.  After this l Read more about What is Cloning?

Detecting a Transposon Tag in Arabidopsis

This lab - produced by the DNA Learning Center and available at http://www.greenomes.org/ - allows students to investigate a gene in Arabidopsis to analyze the molecular relationship between genotyes and phenotypes.  It also helps them understand the use of transposable elements to mutagenize and tag genes as well as the role of homeotic genes i Read more about Detecting a Transposon Tag in Arabidopsis

Decoding a DNA Sequence with Java

Students will write a Java program to read a DNA sequence from either the keyboard or a text file. Then they will display the protein sequence that is produced. Students will simulate the mutation of a single location in the DNA sequence to determine the effects of that mutation. Finally, students will look for the locations of a specific DNA sequence.

A Progression of Computer Science Problems with Bioinformatics as the Context

This activity, a question set for teaching basic computer science ideas via bioinformatics, provides a variety of problems that build on students abilities in both computer science and bioinformatics. The questions get progressively more difficult and build off previous problems although any could be used as a stand alone as well.  Read more about A Progression of Computer Science Problems with Bioinformatics as the Context

Determining Relationships in Families using Gel Electrophoresis

A daughter thinks she’s adopted and wants to determine if her parents are her biological parents.  Students discover how gel electrophoresis is used to help the daughter determine if she is adopted or not.  In addition, students apply previously learned material (pedigree, Punnett square, etc.) to help understand the process and content.  Read more about Determining Relationships in Families using Gel Electrophoresis
