Gene Control in Prokaryotes
In this gene control worksheet, students 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.
Curated OER
ISOLATION OF DNA FROM ONION
Students perform a lab in which they extract DNA from onion cells. Students break through the cell and nuclear membranes and then break down the protein that the DNA is wrapped around.
Curated OER
Study of the Cell
Students draw a diagram to show the fluid mosaic model of a membrane. They explain how hydrophobic and hydrophilic properties help membranes hold their shape. They identify the functions of different cell membrane proteins as well.
Curated OER
DNA and RNA
Tenth graders research the history and discovery of DNA. Using their text, they label a basic DNA structure and the composition of genes. They explain how RNA and DNA differ from one other and discuss the processes of transcription and...
Curated OER
Characterizing Drosophila Mutants
Students 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...
Curated OER
Organs to Go...
Students explain the principles of experimental design and reinforce the steps of the scientific method. Each group of students create a "slush" type mixture to store a chicken liver.
Curated OER
How to Conquer a Genetic Disease
Students study the details of DNA restriction analysis and how RFLP's are used to locate genes on a map of DNA.
Curated OER
DNA Extraction Laboratory Experiment
Students 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...
Curated OER
SEPARATION OF A STARCH-GLUCOSE MIXTURE USING GEL FILTRATION
Students make a starch-glucose solution and pour it through gel in order to separate the starch from the glucose. They examine how starch is a larger molecule than glucose and test for the presence of these substances using other...
Curated OER
Replication of DNA
In this replication of DNA worksheet, students match the correct definition of DNA replication to the terms given. Students also complete given statements with the correct term in the space provided.
Curated OER
Wolf Pack in a Bottle
Students participate in an activity of a mock electrophoresis using paper chromatography to study DNA and genetic restriction mapping.
Curated OER
Effects of ATP and Ions on Rabbit Psoas Muscle
Students prepare single strands of muscle cell. They microscopically examine muscle cells and identify bands of darker and lighter proteins. They predict, observe, describe and quantify the effects of ions and ATP.
Curated OER
Protoplast Production (Plant Cells Without Walls)
Students explore the spherical protoplasts of plants. Students observe that plant cells have a plasma membrane in addition to the cell wall. Students plasma membranes, solutes and organelles.
Curated OER
Cell Transformation in Tobacco Leaf Disks
Students review the basic principles of plant cell structure, tissue culture, sterile technique, and cell transformation. Next students complete a plant transformation experiment using whole plant material in order to view evidence of...
