Around 50 million years ago, the mammalian ancestor of today's whales returned to the ocean. In this genomics science fair project, you will use mitochondrial protein sequencing to trace the evolution of whales and identify their closest...

Given illustrations or partial DNA sequences, students will identify changes in DNA and the significance of these changes.

This site is an advanced level hands-on activity to explain the Di-deoxy sequencing of DNA.

For this activity, students create a bracelet of beads using DNA code. Each letter represents an amino acid and is three beads. The authors suggest that even younger students would enjoy this activity, although older students will...

Do you like solving mysteries? In this experiment, you can find out how a DNA fingerprint can help you figure out whodunit. The answer might just be in the "sequence" of events.

Find out about the process of transcription, where the DNA sequence of a gene is transcribed to make an RNA molecule.

Get an overview of operons, regulatory DNA sequences, and regulatory genes. Also, explore repressor and activator proteins.

Brief descriptions of four complex methods of DNA profiling in plants. Some advantages of DNA fingerprinting are also listed.

This lesson plan focuses on differences in the amino acid sequence of hemoglobin and myoglobin proteins. They use the number of differences to create a phylogenetic tree.

This video segment from NOVA: "Cracking the Code of Life" explores the genetic similarities and differences among organisms.

Ever used a pair of molecular scissors? Restriction enzymes are molecular scissors that cut DNA into pieces. Find out which enzymes will cut, and where by making a restriction map. Then you can figure out what will happen if you change...

All animals have a genome, but do they all have genome projects? Find out which animals are currently having their genomes sequenced and how much we know already by performing some simple bioinformatics data digging.

Explains the goals of the Human Genome Project. It also explains some of the ethical, legal and social challenges associated with this new technology.

Learn about a major function of cells, protein synthesis. Find out about the process in which cells manufacture this biochemical compound.

Explains what chromosomes are, their structure, their functions within a cell, and the health impact of mutations in a gene sequence.

A start codon is a nucleotide triplet in a genetic sequence that occurs at the start of a protein's synthesis. Read about how this works and how a mutation can sometimes occur.
