How Cells Divide: Mitosis vs. Meiosis by Rick Groleau As viewed from a human perspective, nature has done some ingenious engineering to overcome some of the obstacles it has faced. Take the evolution of sex, for instance. To make the move from asexual to sexual reproduction, nature took a system by which parent cells reproduced simply by dividing (asexual reproduction) and altered it to allow two parent cells to combine to create offspring (sexual reproduction).
Virtual Labs The links on this page are all VIRTUAL LABS offered by the Glencoe textbook company. These labs give the students the adventure of laboratory experimentation without costly supplies, worrisome environmental and safety issues, or time-consuming clean up. They are from all different areas of science: Biology, Physics, Genetics, Earth Science, Physical Science, and Chemistry. Trying to Fool Cancer Photo CLEVELAND — WHEN it airs on Monday, the Ken Burns-produced documentary “Cancer: The Emperor of All Maladies” will emphasize how much more we now know about the genetic basis for . This year, according to President Obama, cancer research and funding will focus on so-called precision, personalized or targeted medicine — using cancer’s molecular underpinnings to develop drugs that attack the genes or gene products that make up cancer’s factory while sparing normal cells. What a beautiful concept. The problem is, cancer is rarely that simple, or that easily fooled. Three recent studies, all published or presented late last year, highlight the challenges of building a national cancer therapy policy around precision medicine.
BioBuilding: Synthetic Biology for Teachers PDF of this page BioBuilding for Teachers Welcome! Resources for Teaching Biology The Sourcebook for Teaching Science This book provides science educators with a comprehensive selection of innovative tools, activities, and high-quality instructional resources for enlivening lessons across the science disciplines. It features over 300 classroom-ready activities ranging from word-based problem-solving exercises to hands-on laboratory experiments and includes examples drawn from biology, physics, chemistry, and the geosciences, all linked to National Science Education Standards. The chapter titles and related resources may be found in the column on the right.
Minds-on Activities for Teaching Biology The resources listed below include: minds-on, hands-on activities and minds-on analysis and discussion activities for teaching biology to high school and middle school students and students in non-major college biology coursesoverviews of important biological topicsgames for learning and review. Many of these activities are explicitly aligned with the Next Generation Science Standards, BioInteractive Search Results Click & Learn This Click and Learn explains how DNA sequences can be used to generate such trees, and how to interpret them. West Nile virus infects mosquitoes, birds, and people—with very different consequences. Lactose tolerance, sickle cell anemia, and bitter taste perception are three examples of recently evolved human traits. Lactase persistence results from a mutation that changes how transcription factors interact, thereby affecting gene expression.
DNA with a Twist Researchers show that DNA supercoils are dynamic structures that can “hop” long distances, a phenomenon that could affect gene regulation. iStock, alengo Scientists’ understanding of how long strings of DNA are packaged into tiny spaces just got a little more complicated.
