Enzyme-Catalysed Synthesis
Enzymes: not just for breaking chemicals apart. Young biologists perform an experiment on potatoes. They first remove starch from potato extract. They then add the resulting liquid to samples of glucose-1-phosphate, glucose, maltose, and...

Enzymes and Catalysts
Students discuss the functioning of the digestive system and the specific enzymes present. They observe the action of amylase on starch to identify characteristics of enzymes then perform an experiment on the effects of temperature on...

Catalysts and Enzymes
Biochemists experiment with the oxothermic decomposition of hydrogen dioxide by adding manganese dioxide. They observe how pepsin enhances the action of acid on the digestion of egg white proteins. They use yeast to make bread rise. All...

Cloning of Plasmid and Spinach DNA
Students ligate fragments of genomic DNA from spinach into a vector plasmid. They perform a restriction enzyme digestion. Student use a ligated DNA molecule to transform E. coli cells. Students analyze their procedures and outcome of...

The Cloning of Plasmid and Spinach DNA
Students will first extract genomic DNA from spinach and perform a restriction enzyme digestion on both the spinach DNA and the plasmid using the same restriction enzyme. They then ligate the cut plasmid DNA with the cut spinach DNA in...

Beyond Mendel's Laws of Inheritance
This PowerPoint jumps right into the details of unusual traits and how they are coded. The epistasis patterns in Labradors are used as a main example, and many instances of polygenic inheritance malfunctions are explained. All of this...

Heredity And Environment
Students complete a pre-test on the relationship between heredity and the environment. As a class, they write down descriptions of themselves and identify which traits can be changed and not changed. In groups, they determine which genes...

Characterizing Drosophila Mutants
Learners investigate wild-type and several mutant varieties of Drosophila melanogaster, which are characterized and distinguished according to pteridine pigments. They discoverthat paper chromatography of the wild-type Drosophila results...
