Young scholars create DNA models using colored construction papers. In this biology lesson, students identify enzyme restriction sites. They model how DNA plasmids replicate when taken up by a bacterial cell.

For as small as they are, there sure is a lot of information for young scientists to learn about bacteria. Help simplify the subject with this instructional presentation that explores the structure, nutrition, and reproduction of...

After the lab, you'll be able to solve this analogy: Natural selection is to vertical transfer of genes as ___ is to the horizontal transfer of genes. Young biologists conduct an experiment on E. coli bacteria to explore the process of...

In this bacteria worksheet, students fill in the blanks with the correct word. Students then label the structures found on a bacterium.

Learners participate in biology demos. In this biology lesson, students explain how energy is released in the ATP cycle. They demonstrate DNA replication process.

Students construct various virus models using Fruit loops and Alphabits to represent nucleotides and molecules. They constructs capsomeres using shoes as the capsomeres and discuss various viruses.

This site is part of an "Online Biology Book" and contains excellent text and visuals. Discusses F and R plasmids and includes great illustrations. Well organized and clear.

In this lab, students will transform E. Coli bacteria to be resistant to ampicillin and to glow green. Students will use genetic engineering techniques to insert plasmids into the bacteria. The site contains background reading,...

Learn about the transfer of plasmid DNA into bacteria. Also find out how bacteria are selected, and how proteins are produced and purified.
