In this gene control worksheet, learners use the example of the lactose operon structure to describe what happens when this structure is absent or mutated. This worksheet has 21 fill in the blank statements.

Students engage in a activity that is about the DNA molecule and focuses upon the sequencing of proteins to identify individuals. They conduct research using a variety of resources and then complete the activities included in the 3 parts...

Students model recombination in DNA. They color the DNA sample and cut it out. Students use their "restriction enzymes" to cut the DNA into specific fragments. They separate the fragments using the "gel electrotrophoresis." Students...

Students work with a partner to answer any unanswer questions on their review sheet. They work in groups of 4 to make flash cards as study aides. Students play a review game for the remaining of the class period. The winning team...

Students study genes, DNA and medical research. They watch "The Code of Life" video and answer discussion questions regarding the transcription and translation of DNA and how errors in these processes and mutations in DNA can produce...

Students use scientific methods to investigate the concept of DNA. They observe the DNA of human cheek cells. This is done with the use of a lab experience. Students record their observations and reflect upon on how each organism is...

Students will illustrate how restriction enzymes work by piecing together parts of a puzzle. Then they apply this knowledge to help them analyze genetic evidence from the scene of a crime as well as to help them comprehend how a DNA...

Pupils will visualize how DNA is extracted from cells by performing a simple laboratory experiment. They will then use this knowledge to further understand how scientists are using DNA extraction to try to clone human cells, and to...

Students examine the entire DNA base sequence of the human adenosine deaminase gene after it is printed out from the source disk provided. The enormous length of a single gene as well as the immense difference in length between intron...

At this site see an online visual of meiosis, fertilization, and inheritance and play a game.

Students have the opportunity to work through a problem set over Eukaryotic genes. Correct answers are reinforced with a brief explanation. Incorrect answers are linked to tutorials to help solve the problem.

In this project, you'll learn how to isolate DNA from onion cells, separating it from other cellular components in a manner that still preserves its structure and sequence. In the end, you'll have enough DNA to see with the unaided eye,...

Imagine that a biologist arrived at your big family reunion and had no idea who were sisters, cousins, aunts, uncles, etc., but tried to sort it out by how all of you look. Just based on how you look, would s/he be able to guess whether...

The DNA in our cells contains our "blueprints," but it's the proteins in our cells that do most of the work. The Human Genome Project has allowed us to start reading the blueprints, but we still don't understand what most of the proteins...

When biologists want to separate different pieces of DNA, RNA, or proteins they use a technique called gel electrophoresis. In this science project you'll build a gel electrophoresis chamber and use it to discover how many components are...

Imagine that a biologist arrived at your big family reunion and had no idea who were sisters, cousins, aunts, uncles, etc., but tried to sort it out by how all of you look. Just based on how you look, would s/he be able to guess whether...

This is a project about the "molecular alphabet" of DNA. With just four "letters," it manages to keep track of the plan for an entire person, and keep a complete copy in nearly every cell. This project will help you start learning this...

An explanation of genomes in regards to the amount of DNA compared to the number of chromosomes in different organisms. Additional discussion focuses on how the human genome is different from other species.

This lecture covers the topic of life now and into the future, including the role genetic engineering will play.

Which dictates our existence? Is it our genetic makeup or the environment we grow up in? Kevin Davies offers an update on this long-standing debate, from the NOVA: "Cracking the Code of Life" Web site.

Charles Darwin's theory that all living organisms are connected in some way has been confirmed through intense studies over centuries. Understand the similarities that bond all things living to the same family tree by checking out this...

An animation introducing the basic concepts of cells, DNA, recessive inheritance, and Punnett squares.

A good site that begins with the background and branches into the structure, function and applications of technology. This version of the page requires Java, and should open some applets that allow you to see the structures in 3-D.

Learn how to gain access to MEDLINE, the National Library of Medicine database of citations and abstracts in the fields of medicine, nursing, dentistry, veterinary medicine, health care systems, and preclinical sciences.
