PLoS Biology : Publishing science, accelerating research A Peer-Reviewed, Open Access Journal Current Issue PLOS Biology is a peer-reviewed, open-access journal featuring research articles of exceptional significance in all areas of biological science, from molecules to ecosystems. Microscope Imaging Station. Stem Cells: Cells with Potential. What are stem cells? Your body contains over 200 types of cells, each with a specific job: blood cells carry oxygen; muscle cells contract so that you can move; nerve cells transmit chemical signals. The job of a stem cell is to make new cells. It does this by undergoing an amazing process—differentiating, or changing into another type of cell. Each time a stem cell divides, one of the new cells might remain a stem cell while the other turns into a heart, blood, brain, or other type of cell. Stem cells are the source, or “stem,” for all of the specialized cells that form our organs and tissues. Next: Why invest so much in studying stem cells?

The PCR Method - a DNA Copying Machine Lists of Nobel Prizes and Laureates The PCR Method - a DNA Copying Machine Play the Eye of the Donkey Game About the game PCR is a method by which a few fragments of DNA can be duplicated into millions in a couple of hours. The Nobel Prize The 1993 Nobel Prize in Chemistry was awarded for the invention of PCR, a method that made it possible to copy a large numbers of DNA fragments in only a few hours.

Scientists observe single gene activity in living cells in detail for first time Researchers at Albert Einstein College of Medicine of Yeshiva University have for the first time observed the activity of a single gene in living cells. In an unprecedented study, published in the April 22 online edition of Science, Einstein scientists were able to follow, in real time, the process of gene transcription, which occurs when a gene converts its DNA information into molecules of messenger RNA (mRNA) that go on to make the protein coded by the gene. Robert Singer, Ph.D., co-director of the Gruss Lipper Biophotonics Center at Einstein and professor and co-chair of anatomy and structural biology, is senior author of the paper. The study's lead author is Daniel Larson, Ph.D., previously a member of Dr. Using florescent proteins, the researchers were able to follow mRNA activity by inserting DNA sequences into a gene in live yeast cells. This research was funded by the National Institutes of Health and the National Institute of General Medical Sciences.

Cell Models For life all cells have basic needs. Cells have diverged in their structure and function to accommodate these survival requirements. Here are some KEY TERMS to help you think, explore and search for similarities and significant differences that have become the characteristics of eukaryote (animal, plant) and prokaryotic (bacteria) cells. Examples might be searching: eukaryote prokaryote reproduction or animal plant cell energy. Reproduction / cell division Energy trapping, storage and consumption Form / shape / structure Cell specialization Compartmentalization of cell functions Communication within and beyond the cell Cell / organism survival DAVID: Gene Functional Classification What does this tool do? Quickly translate given gene IDs to corresponding gene names in a batch way Provide links for each genes to DAVID Gene Report for in-depth information Search functionally related genes within user's input gene list or genome Key Concepts of "Search Related Genes" Any given gene is associating with a set of annotation terms. If genes share similar set of those terms (annotation profile), they are most likely involved in similar biological mechanisms. Find Related Genes Tool is very different and complementary to the common gene clustering methods, such as homologous genes based on sequence similarity; protein families based on one common biological activity.
