Students work with whole plant material and are not required to measure small quantities, yet they can see evidence of transformed plant cells (plant cells that have genes from bacterial plasmids). This is a laboratory suitable for students who are familiar with the basic principles of plant cell structure, tissue culture, sterile technique, and cell transformation (bacterial infection, plasmid vectors, marker genes, selection medium, and enzyme activity assays).
In this genetics worksheet, students answer a variety of questions about inheritance, DNA, the genetic code, genes, sexual and asexual reproduction, mutations, protein synthesis and genetic engineering.
Students discuss and compose a document discussing the transmission of the Huntington's gene- dominant or recessive, sex linked, etc. Additionally, they ought to consider Dr. Wexler's own odds for contracting the disease.
Mendels laws of Genetics are extended here with examples of traits that are completely controlled by just one gene. Malfunctions such as albinism and baldness can therefore be tracked and will demonstrate inheritance patterns to your class. This slideshow will really clarify some discussion points on the nature and nurture debate and could start other topic research.
Students are asked to recount their greatest hopes and fears concerning DNA. One article states how worthwhile gene manipulation in plants can be. Classroom discussions arise after reading one article on this issue.
Young scholars are asked to use their imaginations to take the idea of biotechnology one step further. Before beginning this activity students read and complete a report on the book "Jurassic Park," which deals with the use of biotechnology to recreate animals (dinosaurs). There assignment is to use genetic engineering to create a fantasy animal utilizing genes from present day animals or plants.
Learners model traits on genes using colored paper and tongue depressors to represent chromosomes. In this heredity lesson plan, students use their "chromosome sticks" to understand chromosome pairs, genes, dominant traits, recessive traits, heterozygous, genotypes and phenotypes. Learners create different gene combinations using their chromosome sticks.
Students research genetic adaptations. In this chromosome lesson plan, students investigate dominant and recessive genes using spiders indigenous to Hawaii. Students create Punnett squares to determine the probability of passing specific genetic traits to its offspring.
How are the reactions between American and European consumers different when it comes to genetically modified foods? Use the New York Times article "Consumers in Europe Resist Gene-Altered Foods" to inform your middle schoolers about the controversy, as well as to compare the reaction in America. Lead your class in a debate about whether or not genetically modified food should be available in a grocery store.
High schoolers complete a study guide using a website which is an animated primer on DNA, genes, and heredity. The Web site is organized around key concepts. The web links and study guide are included.
Students observe how chance affects which genes appear in gametes (Mendel's Law of Segregation). They use beans to represent the recombination of alleles during fertilization.
Students complete a lab based on how chance affects which genes appear in gametes as in Mendel's Law of Segregation. They review the theories, vocabulary words, and historical background of Gregor Mendel's work with pea plants. They complete lab worksheets and submit for grading.
The metaphors used here to describe the "cut and paste" procedures for genetic engineering will really help your biologists in their understanding of restriction enzymes and DNA. The uses of genes that are isolated and incorporated into plasmids are discussed and will help your students learn the real life opportunities and application of biotechnology.
High schoolers solve the following 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?" They use the constructivist approach to studying as they work in teams to design and conduct an experiment that solves this natural selection "problem."
Supplementing the review of mitosis and meiosis, the detailed slides give information about growth factors, cell communication, and regulator genes. A fascinating topic, your class will be inspired by the applications and developments of science.
Students use analogies to show the relationships among cell, nucleus, genes, chromosome, ribosome, replication, mitosis, transcription, translation, DNA, RNA, amino acids and proteins, genotype, phenotype, and genetics vs. environmental causes of cell defects.
For this heredity worksheet, students will create 3 Punnett squares to determine the genotype and phenotype of the offspring from specific breedings. Then students will answer 7 true or false questions based on chromosomes and sex-linked traits. Then students will answer 4 short answer questions about environmental influences on gene expression.
Young scholars investigate the process of genetic engineering. In this genetic engineering lesson plan, students use paper models of DNA and plasmid bacterium to investigate the process of replicating DNA, splicing genes from DNA, and inserting genes of donated DNA into a plasmid.
Students start to think of evolution in terms of populations. The class follows a cartoon scenario of a rabbit population in which there is selection and change of gene frequency. They receive copies of the scenario or the whole thing can be done on an overhead.
For this reproduction worksheet, learners read four paragraphs about reproduction and match eight terms to their definitions. Topics include sexual reproduction, chromosomes, genes and asexual reproduction.
