The Twisting Tale of DNA

(View Complete Item Description)

This brief video lesson describes DNA and its role and importance in living organisms. This is a very comprehensive overview of how DNA determines form and function, manages protein synthesis within individuals, and ultimately drives evolution. Discussion/assessment questions and suggested supplemental resources are also included.

The Development of Atomic Theory

(View Complete Item Description)

In this lesson, students will work in small groups to read and analyze a primary source using a set of questions designed to help them understand the writers' viewpoints. Students will then explain their findings to their classmates. Finally, each student will produce a written essay that explains how and why scientific understanding of the atom has changed over time.

BLAST Assembled Genomes

(View Complete Item Description)

This resource goes with the lesson plan "Alien Encounters -- Transcription and Translation" . Students can use this resource to look up the DNA sequence for a specific disease of their choice, then enter the DNA sequence and find the amino acid sequence for the disease. Students can prepare a poster of a disease which would include information about the disease, the DNA sequence, RNA strand and amino acid chain.

Building a Protein

(View Complete Item Description)

This hands-on activity is designed for students to demonstrate the concepts of bonding amino acids to create proteins, and to model protein synthesis. This activity cab be used as an assessment of the students' understanding of peptide and disulfide bonds formed during protein synthesis, and the structure of an amino acid (R-group plus the common structure that all amino acids share). Students will demonstrate the process of dehydration synthesis by combining amino acids. They will synthesize one molecule of the protein ADH (antidiuretic hormone) by reading the mRNA sequence, cutting out the -OH on the carboxyl group on amino acid one, and the -H on the amino group of amino acid two. These two pieces (-OH and -H) will combine to form a water molecule. The students will connect the two amino acids by taping a peptide bond label between the carbon of the carboxyl and the nitrogen of the amino group on amino acid. This process is continued until the stop codon on the mRNA is read. If the synthesis is done correctly, the student will produce eight peptide bonds creating one chain, and eight molecules of water. If this activity is used for biology, the tRNA, and rRNA molecules can be added to the process.
