The authors of the research presented in this special collection used the first description of the B73 maize genome to probe some of the most intriguing questions in genetics and plant biology. Read about maize centromeres, new insights into transposon types and distribution, the abundance of very short FLcDNAs encoding predicted peptides, and many other "genetic jewels" contained herein.

This unit looks at two topics that are of immense worldwide social, economic, ethical, and political importance -"addiction' and"neural ageing'. You will develop a Master's level approach to the study of specific issues within these two important subject areas.
"Normally, an animal gets half its DNA from its mother and half from its father. But Dolly had three mothers: one mother gave Dolly her DNA; one supplied an egg; and the third, her surrogate mother, gave birth to her. Dolly is an identical twin of the mother who gave her her DNA. But Dolly is six years younger."This kid-friendly Web page helps kids understand how and why Dolly was cloned, and understand the potential benefits of cloning as well as the controversy it raises.
This annotated slideshow adapted from KET's Electronic Field Trip to the Forest illustrates how blight decimated the American chestnut tree and the methods scientists use to identify and pollinate the remaining trees to create blight-resistant trees. ***Access to Teacher's Domain content now requires free login to PBS Learning Media.
In this anatomy version of jeopardy, you will be quizzed on the following topics: biomolecules, lipids, carbohydrates, DNA and RNA, and proteins. Good Luck!
Antibiotics save people’s lives...and make bacteria stronger and more likely to kill us. What is the best practice to balance these conflicting issues? In this problem-based learning module, the students will be evaluating real-life medical situations in conjunction with actual staff at those institutions and offering action plans to be ‘implemented’ there. In order to accomplish this, the science unit will be interlocking with social studies and a language arts unit that will have them identifying target audiences and sculpting a way to present their findings. This unit has the potential to be a full problem-based unit as well as highly interdisciplinary--it’s connected to full units in social studies and language arts which stand alone but can be fully integrated if desired.
This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they take a look at genetics and DNA research with six AMNH scientists' journals. The Humpback Whale Journal takes kids to Madagascar to meet this endangered species. The Spotted Owl Journal takes kids to California for a look at these birds who are at risk because their forest homes are being cut down. The Sumatran Tiger Journal takes kids to Indonesia for a look at this genetically unique tiger. The Ruffed Lemur Journal also takes kids to Madagascar, but this time they venture inland to meet the endangered primate. The Pacu Journal takes kids to Brazil to meet this vegetarian relative of the meat-eating piranha. The St. Vincent Parrot Journal takes kids to the West Indies to meet the rare, colorful birds that are further at risk because of smuggling.
Students construct paper recombinant plasmids to simulate the methods genetic engineers use to create modified bacteria. They learn what role enzymes, DNA and genes play in the modification of organisms. For the particular model they work on, they isolate a mammal insulin gene and combine it with a bacteria's gene sequence (plasmid DNA) for production of the protein insulin.
In this visually dazzling talk, Jonathan Drori shows the extraordinary ways flowering plants -- over a quarter million species -- have evolved to attract insects to spread their pollen: growing 'landing-strips' to guide the insects in, shining in ultraviolet, building elaborate traps, and even mimicking other insects in heat. Jonathan Drori commissioned the BBC's very first websites, one highlight in a long career devoted to online culture and educational media -- and understanding how we learn. A quiz, thought provoking question, and links for further study are provided to create a lesson around the 14-minute video. Educators may use the platform to easily "Flip" or create their own lesson for use with their students of any age or level.
Students toss coins to determine what traits a set of mouse parents possess, such as fur color, body size, heat tolerance, and running speed. Then they use coin tossing to determine the traits a mouse pup born to these parents possesses. Then they compare these physical features to features that would be most adaptive in several different environmental conditions. Finally, students consider what would happen to the mouse offspring if those environmental conditions were to change: which mice would be most likely to survive and produce the next generation?
Bioethics is the study of the moral implications of new and emerging medical technologies and looks to answer questions such as selling organs, euthanasia and whether should we clone people. The series consists of a series of interviews by leading bioethics academics and is aimed at individuals looking to explore often difficult and confusing questions surrounding medical ethics. The series lays out the issue in a clear and precise way and looks to show all sides of the debate.

" This course does not seek to provide answers to ethical questions. Instead, the course hopes to teach students two things. First, how do you recognize ethical or moral problems in science and medicine? When something does not feel right (whether cloning, or failing to clone) ŰÓ what exactly is the nature of the discomfort? What kind of tensions and conflicts exist within biomedicine? Second, how can you think productively about ethical and moral problems? What processes create them? Why do people disagree about them? How can an understanding of philosophy or history help resolve them? By the end of the course students will hopefully have sophisticated and nuanced ideas about problems in bioethics, even if they do not have comfortable answers."
This exercise contains two interrelated modules that introduce students to modern biological techniques in the area of Bioinformatics, which is the application of computer technology to the management of biological information. The need for Bioinformatics has arisen from the recent explosion of publicly available genomic information, such as that resulting from the Human Genome Project.
Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.
By the end of this section, you will be able to:Explain the relationship between genotypes and phenotypes in dominant and recessive gene systemsDevelop a Punnett square to calculate the expected proportions of genotypes and phenotypes in a monohybrid crossExplain the purpose and methods of a test crossIdentify non-Mendelian inheritance patterns such as incomplete dominance, codominance, recessive lethals, multiple alleles, and sex linkage
