در این قسمت،ساختمان پوشش سلولی باکتریهای گرم مثبت،گرم منفی و اسید-فست مورد بحث قرار می گیرد. ترکیب و فعالیت ماکرومولکولهای منحصربفرد پوشش سلولی و بیوسنتز آنها نیز شرح داده خواهد شد.علاوه بر این در مورد اندوسپورها که از جهاتی غیرمعمول هستند(از جمله ساختار پوشش سلولی ) نیز بحث می شود.
"DNA has come a long way." James D. Watson, Nobel Laureate
What is DNA and what are the issues and history surrounding the mapping of the human genome, eugenics, discoveries of genes that influence human health and behavior, creating tailored DNA molecules and other scientific and ethical aspects? DNA Interactives will engage you in the stories and science so you can discover for yourself the answers and consider the consequences in genetics.
DNA Interactive (DNAi), developed by the Dolan DNA Learning Center at Cold Spring Harbor Laboratory, provides video, animations, and other resources that will engage your students, improve their understanding, and reinforce what they’re learning in the classroom.
Understanding DNA is a real challenge. In North Carolina, students from seventh grade science through agriscience and AP Biology are asked to explore the structure and function of DNA, investigate inheritance and reproduction, and analyze the molecular basis of heredity. A little online multimedia can make this complicated topic more palatable and accessible!
DNAi’s instructional resources are grouped into topics covering the history, science, and applications of genetics. The Timeline gives a chronological overview of DNA research and discovery from the earliest work with fruit flies through the recent mapping of the human genome. The interactive timeline provides links to deeper exploration of the material: as you mouse over topics, images, and illustrations, you see a description of the content and format they represent and can then click to read or watch what interests you. The sections of the website on the science of genomics help students understand not only the discoveries but the process of discovery and the scientists who made them. Code explains the structure of DNA and how the code is read, copied, and controlled. These problems are presented as mysteries solved by scientists, with students invited to play along. For each module (copying, reading, and controlling the cold) there is a discussion of the problem, an overview of the players (the scientists), an explanation of the “pieces of the puzzle” found by the scientists, and finally “putting it together” — how the problem was solved. The sections of DNAi on Manipulation and the Genome use a similar approach.
Applications invites students to consider forensic mysteries, apply genetic research to health care, and research human origins. For example, Recovering the Romanovs explores the genetic traits of the Romanov family, the last imperial family of tsarist Russia, and then applies this research to solving the mystery of Anna Anderson — was she the missing Anastasia Romanov? Visually appealing and supported with a glossary, this module would work well with middle and high school students looking for connections between science and the real world.
Finally, Chronicle combines historical context with applications, in an examination of eugenics. Sections on eugenics as a “solution” to societal problems, sterilization programs, and Third Reich attempts at “improving” the race by sterilzing or executing mental patients provide opportunities for discussion and debate about bioethics and our roles and responsibilities in shaping our own genetic development. DNAi features a custom interface for teachers. Free registration enables you to build lessons and send your students directly to a customized DNAi Class Page with content you have selected. Building lessons that include 2D interactive animations, 3D animations (with or without audio), and video interviews from the website is simple and straightforward, and you can reorder, add, or delete materials as you choose. As you select materials for the lesson you may easily reorder the elements, as well as add or delete. Lessons can be built ahead of time and stored on the site for later use by your students. Also on the class page are links to related websites DNA News updates, which you can edit as you choose. Finally, the MyDNAi teacher page includes an extensive teacher’s guide with standards correlations, printable student materials, and even an origami DNA model.
