Geiger, Jon R. – American Biology Teacher, 1984
Discusses techniques involved in producing recombinant DNA. Also discusses implications of the new genetic technologies and prospects for the future. (JN)
Descriptors: Biology, College Science, DNA, Futures (of Society)
Peer reviewed Peer reviewed
Krider, Hallie M. – American Biology Teacher, 1984
Various typs of DNA are discussed. Areas considered include highly repetitive and satellite sequences, genes encoding, ribosomal RNA, histone protein genes, and dispersed repeated genes that jump. Regulated genetic misbehavior, structure and use of unique genes, and higher order complexities of chromosomes are also discussed. (JN)
Descriptors: Biology, Classification, College Science, DNA
Peer reviewed Peer reviewed
Freeman, Lenore Gardner – American Biology Teacher, 1984
The advantages of DNA hybridization procedures for classroom and clinical use can now be realized by the recent development of nonradioactive DNA labeling/detection procedures. These methods (which are described) can replace the use of isotopes in standard DNA hybridization procedures. (JN)

Mertens, Thomas R., Comp. – American Biology Teacher, 1984
Presented is an annotated bibliography of 24 books on DNA and genetic engineering. Areas considered in these books include: basic biological concepts to help understand advances in genetic engineering; applications of genetic engineering; social, legal, and moral issues of genetic engineering; and historical aspects leading to advances in…

Spain, James D., Ed. – American Biology Teacher, 1984
Discusses some of the major genetic information processes which may be modeled by computer program string manipulation, focusing on replication and transcription. Also discusses instructional applications of using string models. (JN)
Descriptors: College Science, Computer Oriented Programs, Computer Software, DNA

Larson, Garrett; And Others – American Biology Teacher, 1984
Describes current methods for the synthesis of DNA. Also describes the use of DNA as a highly specific molecular probe and as an agent for the mutation of genes. (DH)
Descriptors: Biochemistry, Biology, Chemical Reactions, College Science
Peer reviewed Peer reviewed
Ruth, Edward B. – American Biology Teacher, 1984
Describes the use of a chart that systematically summarizes three basic steps that involve DNA and its decoding in both eukaryotic and prokaryotic cells: replication; transcription, and translation. Indicates that the chart (mounted on a tranparency) does an adequate job of conveying basic information about nucleic acids to students. (DH)

Silvius, John E. – American Biology Teacher, 1984
Describes a laboratory study in which students evaluate, in ecological terms, different landscapes representing ecosystems under varying degrees of human domination. Also discusses the context within which the study is arranged. (JN)
Descriptors: Biology, College Science, Ecology, Environmental Education
Peer reviewed Peer reviewed
Barman, Charles R., Ed. – American Biology Teacher, 1984
Presented is a recommended sequence for developing a slide-tape presentation. Steps include selecting a topic, determining objectives for the presentation, constructing a storyboard, writing the script, and recording the script. Comments on use of quotation, sound effects, built-in pauses, and use of student voices are included. (JN)

Peer reviewed Peer reviewed
Journet, Alan R. P. – American Biology Teacher, 1982
Describes a simple model to illustrate several aspects of the biochemical origin of life and the process of evolution through natural selection. The model has students predict the outcome of evolution in populations of beads. Instructional strategies using the model are also discussed. (Author/JN)
Descriptors: Biology, College Science, Evolution, High Schools
Peer reviewed Peer reviewed
Core, Earle V., Jr. – American Biology Teacher, 1982
A different approach is used to develop taxonomy concepts. A traditional outline of each phylum under consideration is given to students, together with a series of questions. Students must then determine relationships within the outline by answering the questions. (Author/JN)
Descriptors: Biology, Classification, High Schools, Science Activities
Peer reviewed Peer reviewed
McDermid, Karla J.; Naiman, Robert J. – American Biology Teacher, 1983
Physical, chemical, and biological effects on macrophytes (aquatic plants) on the freshwater ecosystem are discussed. Research questions and issues related to these organisms are also discussed, including adaptations for survival in a wet environment, ecological consequences of large-scale macrophyte eradication, seasonal changes in plant…

Peer reviewed Peer reviewed
Loehr, Karen A. – American Biology Teacher, 1983
Describes a laboratory exercise in which students select and identify an organism, study it as it interacts within its environment, collect further information through library research, and bring the organism (alive, preserved, or photographed) to lab for a five-minute presentation. (JN)
Descriptors: Animals, Biology, College Science, Ecology
Peer reviewed Peer reviewed
Barman, Charles R. – American Biology Teacher, 1982
Describes a demonstration and role-playing activity focusing on differences between living/dead, definitions of living/dead, and situations in which active euthanasia could be morally right. (Author/JN)
Descriptors: Death, Demonstrations (Educational), Elementary School Science, Elementary Secondary Education

Leonard, William H.; Snodgrass, George – American Biology Teacher, 1982
Concepts to be developed, objectives, and student instructions are provided for an activity useful as an introduction to or review of Mendelian genetics and sex determination. Universal codes (read by optical scanners at supermarket checkout stands) from soup can labels are used as chromosome maps during the activity. (JN)
