A useful introduction is given to recap Bronsted-Lowry acid base theory before multiple tables are completed. Pupils should be able to calculate the pH or concentration of certain solutions and also provide the definitions for some chemistry terms. The varied nature of the questions ensures that they get a good review of the topic. This instructional activity could even be used as a test in its own right.
In this gene cloning worksheet, students are given a gene sequence of DNA, plasmid DNA, 3 restriction enzymes, their cut patterns and a DNA ligase. They answer 6 questions about the results of using different restriction enzymes to cut the gene sequence and how they would go about inserting the gene into the plasmid DNA.
Students examine different levels of organization in biological systems for structure and function relationships. In this biological systems lesson, students use Internet resources to look at structure and function in the eye, the cell, protein synthesis, and sickle cell anemia. Resources and detailed instructions are provided.
In this protein synthesis simulation activity, students practice transcribing a DNA message to RNA. They determine the total possible combinations of bases to make codons. Students practice determining what amino acids are coded for given three bases using the given table. Students work in reverse to determine a DNA sequence by starting with an amino acid message.
In this adaptations worksheet, students read about 3 species that have changed over time to adapt to their environment. Students design a squirrel that has adapted to an island habitat that students are assigned. They describe the squirrel's adaptations and why they are beneficial. Students are given 14 terms for which they must give an example of one species that fits the term.
Students analyze the results of a hypothetical cloning experiment using a restriction endonuclease map obtained from an on-line data source. They answer the question, "How can I tell if the DNA I have obtained from this hypothetical cloning experiment is the DNA I am expecting to get?"
Learners construct DNA fingerprints. In this genetics instructional activity, students watch an on-line gel electrophoresis animation, then they work in groups to use a restriction map to create a restriction enzyme and use that to arrange a DNA fragment. Lesson includes extension ideas.
The lecturer describes how certain characteristics develop. In this case, he discusses eye marking. The impact of environmental factors plays a huge role in the probability of successful reproduction and the fact that favorable genes will be passed on to repeat the same characteristic. A very interesting point is that the level of disease occurring after reproductive years in humans is exponential simply because those occurrences are part of the selection.
Molecular biology masters match terms with descriptions of the components of DNA. They relate other vocabulary terms to each other and they answer questions about the scientists who contributed to our understanding of DNA structure. This is a photocopy of a Holt Biology activity, but you can assign it as a review, no matter which text your class is using.
An excellent review of the very specific stages of mitosis, the detailed slides start with explanations of the directionality of DNA and then develop the concept of daughter strands. The intricate diagrams are intended for experienced biology students with prior knowledge of DNA structure. This would be an excellent slideshow to accompany a related activity such as blotting or electrophoresis.
Students investigate the production of proteins by the DNA. In this protein synthesis lesson plan, students use paper models to explore transcription and translation to make proteins using DNA. Students answer 10 questions to demonstrate their understanding of the simulation and how proteins are made.
By completing this assignment, junior chemists show what they know about chemical equilibrium. They will identify conjugate acid-base pairs, write out dissociation reactions, calculate pH, and more. This is a comprehensive review of the topic, and a worksheet worth giving to your class as practice for an exam.
The various experiments and processes that were completed in the 20th century to further our understanding of DNA are summarized here. There are wonderful slides to popularize the scientists who dedicated their professional life to scientific research. The information about their work will educate and inspire students of biology and of science history.
