String up a message. Pupils string together colored beads to code a word or short phrase. Each color represents one of the four DNA bases. Using a combination of three bases, learners create an amino acid that stand for each letter of...

Before a cell replicates, its DNA must replicate. Take advantage of a hands-on guided lesson to teach budding scientists how this happens. Using a set of nucleotide cards, learners become the DNA and work to create matching strands...

How do reverse transcriptase inhibitors work? Young virologists examine the function of azidothymidine, a drug doctors use to treat HIV patients, during a hands-on modeling activity. Groups create a strand of DNA from an HIV RNA strand...

Get your class to take a closer look at DNA. Pupils conduct research to determine the methods used by scientists to analyze the molecular structure of DNA. The class members investigate different types of molecular imaging along with gel...

Does where we live influence how our bodies express genetic traits? Explore variation in human skin color with an activity that incorporate video and hands-on learning. Individuals model the relationship between phenotypes and genotypes,...

Need an a-maize-ing lesson to show your class how regulatory genes work? If you use the well-written resource, they'll be all ears! Biology scholars discover the gene responsible for the evolution of the modern-day corn plant through a...

A series where students see how to submit a nucleotide sequence, compare it to other sequences using blastn, and interpret some of the results.

This lab illustrates how the order of nucleotides in DNA determines the order of amino acids in proteins. Relates DNA function to that of RNAand provides an exercise to demonstrate how mutations may occur. Includes a lesson plan and...

Use BLAST to identify unknown sequences. GenBank contains over 3 million sequences, with over 14 billion nucleotides. BLAST can be used to compare an unknown sequence to all the sequences in the database, and find sequences that match....
