Students are able to distinguish between transcription and replication. They are able to distinguish between DNA and RNA. Students name some of the proteins and enzymes used in replication and transcription. They are able comprehend the...

Can your biology class crack the Case of the Crown Jewels? Junior forensics experts try their hands at DNA restriction analysis in an exciting lab activity. The lesson introduces the concept of restriction analysis, teaches pipetting and...

Biology stars extract DNA samples from beef thymus and then examine its properties. They use enzymes to digest the DNA samples, and then use electrophoresis to separate fragments. Finally, they discuss methods and principles of...

Students explore DNA and restriction enzymes using fragments of DNA separated by electrophoresis on an agarose gel. They analyze the results to see "whodunit".

Students applied various mathematical analyses to interpret their data. By using the resulting DNA fragment patterns from several enzymes students established a possible evolutionary relationship among the mice.

High schoolers compare different DNA and run a gel electrophoresis.  In this DNA lesson students complete a DNA activity that allows them to better understand its structure and function. 

Students develop and run a laboratory comparing alcohol tolerance in flies with and without the ADH enzyme.

Students explore biotechnology through various activities. In this biology instructional activity, students analyze its pros and cons. They study and read informative articles about biotechnology.

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...

Investigate the relationships between different deep-sea organisms by DNA sequencing. A worksheet provides instructions for DNA sequencing and space to work. They simulate gel electrophoresis by cutting out paper "DNA strands."...

Ms. Strohfeldt did not omit anything when she designed this comprehensive lesson plan on DNA mutation and sex-linked traits. Begin with a pretest as an anticipatory set. Read a case history of the Clark family and the occurrence of...

Students experience a "hands-on" activity to get visual evidence of the physical nature of DNA and the process of DNA purification. They explore one method of chromosomal DNA isolation and DNA extraction.

Suitable for an AP Biology class, the lab found here has teen bioengineers working with plasmids to clone DNA. If you have not done a similar lab, the instructions may be rather difficult to follow. Both the teacher and learner...

Biology learners investigate the effect of sucrose concentration on yeast alcoholic fermentation. During the lesson,they compare and contrast the processes of cellular respiration and alcoholic fermentation. They design an experiment to...

Students explain the processes for separating DNA from tissue and separating complex mixtures.  In this exploratory lesson plan students complete a lab where they extract DNA.  

Students perform a laboratory exercise designed to show how DNA can easily be extracted from onion cells. They conduct an optional test for the presence of DNA using standard lab equipment.

High schoolers explain the process of polymerization. In this chemistry lesson plan, students produce carboxylesterase in the lab. They test its effectiveness in removing the by-product odor.

Students extract DNA from split peas. In this biology lesson, students hypothesize what DNA looks like and perform the experiment to verify their hypothesis. They explain the importance of DNA in living things.

Students demonstrate that many of the enzyme systems needed to break down--and therefore clean up-society's wastes already exist in nature among the decomposers. They select the best starch-munching organisms by altering the environment...

Students demonstrate the path of food in the body. In this biology lesson plan, students conduct an experiment to determine how large the the digestive system is. They name the different organs involved in the digestive process.

Students isolate DNA from different food sources. In this biology lesson, students research DNA extraction. They analyze DNA stands collected from the lab, and compare the differences between each.

Students analyze the calcium content of egg shells as an introduction to the toxic effects of pesticides on biological systems.

Learners investigate stereoisomers using models that can be rotated and manipulated. For this stereoisomers lesson plan, students try to make models of molecules look alike by rotating the bonds. Using a mirror, the teacher demonstrates...

Students identify the steps in a gel electrophoresis experiment and describe the role of enzymes. They examine the relationship between fragment size and migration rate in a gel. They view DNA fragments as well.
