Microarrays: Chipping Away at the Mysteries of Science and Medicine
Students research microarrays on the internet in cooperative groups. Students write an essay describing the use of microarrays in environmental research and in medicine.
Curated OER
Why Do We Need Vitamin C in Our Diet?
Students compare/contrast the DNA sequence data of the rat GULO gene to the inactive human GULO gene. They translate and align the sequences, and propose a scenario to explain the occurrence of an inactive DNA sequence to that of an...
Curated OER
What Can Pseudogenes Tell Us About Common Ancestry?
Students compare/constrast DNA sequence data for a portion of the rat GULO gene to the corresponding sequence in the inactive GULO gene in humans, chimpanzees, orangutans, and crab-eating macaques by identifying the shared sequences in...
Curated OER
If Your Mom Has Big Feet, Will You Have Them Too?
Young scholars describe and apply the Mendellian principles of genetics, focusing predominantly on dominant and recessive genes. They demonstrate how two parents contribute genes and how those genes appear in their offspring. They...
Curated OER
Plant Biotechnology: Controlling Tissue Differentation
Students demonstrate skills of biotechnology stringent aseptic technique and statistical analysis. They describe hormonal control of plant tissue differentiation and relate this to gene expression. Students observe the effects of...
Curated OER
Evolution
In this evolution worksheet, students review genetic variability, gene mutations, biodiversity and adaptations. This worksheet has 22 fill in the blank and 10 short answer questions.
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
Camouflage and Protective Coloration: A Model of Natural Selection
Young scholars collect data and compare whether protective coloration or camouflage provides better biological fitness in a given environment. They simulate predator prey interactions of two different species and use gene frequencies to...
Curated OER
Scientist Simulation
Students imagine themselves working as research scientists completing the end-steps of a molecular research project and interpreting the data. They compare the gene sequences of normal and abnormal mice and evaluate the protein product...
Curated OER
DNA, Protein Synthesis and Mutations
Tenth graders investigate the chemical composition of DNA and RNA and how they work together to synthesize protein. They discover genetic codes, gene chromosome theory, and how the environment influences our appearance.
Curated OER
The Meaning of Genetic Variation
Students investigate variation in the beta globin gene by identifying base changes that do and do not alter function, and by using several Internet-based resources to consider the significance in different environments of the base...
Curated OER
Genetic Disorders
Seventh graders discuss traits, traits that are inherited and how genes and chromosomes carry the code for traits. They research genetic disorders and their link to chromosome abnormalites and write a report on their findings. which...
Curated OER
Beans and Birds: A Natural Selection Simulation
Learners examine the problem concerning the evolution of seed color in pinto bean plants "How does natural selection change the frequency of genes or traits over many generations"? Students work in teams to design an experiment that...
Curated OER
The Code of Life
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...
