The Control of the Cell Cycle

The Control of the Cell Cycle
Lists of Nobel Prizes and Laureates Control of the Cell Cycle Play the Control of the Cell Cycle Game About the game The game is about the different phases in ordinary cell division, mitosis. Between each phase there are several "check points" to make sure that nothing happened to the genetic material on the way. The Nobel Prize The 2001 Nobel Prize in Physiology or Medicine was awarded for discoveries concerning the control of the cell cycle.

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 The Cell and its Organelles Lists of Nobel Prizes and Laureates The Cell and its Organelles Play the Incredible Megacell Game About the game DNA Learning Center Home DNA Learning Center Preparing students and families to thrive in the gene age Catalog List of cognitive biases Illustration by John Manoogian III (jm3).[1] Cognitive biases can be organized into four categories: biases that arise from too much information, not enough meaning, the need to act quickly, and the limits of memory. Cognitive biases are tendencies to think in certain ways that can lead to systematic deviations from a standard of rationality or good judgment, and are often studied in psychology and behavioral economics. There are also controversies over some of these biases as to whether they count as useless or irrational, or whether they result in useful attitudes or behavior. For example, when getting to know others, people tend to ask leading questions which seem biased towards confirming their assumptions about the person. However, this kind of confirmation bias has also been argued to be an example of social skill: a way to establish a connection with the other person.[8]

Phases of Mitosis in Plant and Animal Cells Cell Division Overview Clockwise, from top left: embryonic sea urchin cells, frog skin cells, neuron, 8-cell fish embryo. All of the living organisms on Earth are made up of one or more cells, which are the simplest units of life capable of independent existence and reproduction. Cells have the extraordinary ability to make nearly identical copies of themselves by the process of cell division. Since new cells are only produced by existing cells, cell division is essential for the continuation of life.

The Split Brain Experiments Lists of Nobel Prizes and Laureates The Split Brain Experiments Play the Split Brain Experiments 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. Transcription (genetics) Simplified diagram of mRNA synthesis and processing. Enzymes not shown. Transcription can be reduced to the following steps, each moving like a wave along the DNA. Transcription has some proofreading mechanisms, but they are fewer and less effective than the controls for copying DNA; therefore, transcription has a lower copying fidelity than DNA replication.[2]

Pavlov's Dog Lists of Nobel Prizes and Laureates Pavlov's Dog Play the Pavlov's Dog Game About the game Conditioned reflexes are reflexes you can learn compared to unconditioned reflexes that are built-in, or natural. Nerve Signaling Lists of Nobel Prizes and Laureates Nerve Signaling Play the Nerve Signaling Game About Figure 2 : C.Elegans: : Mining the functional genomic landscape : Nature Reviews Genetics a | Protocols for administering RNAi in C. elegans. b | Examples of RNAi phenotypes. Top, a control, wild-type embryo at the four-cell stage (left) and an mcm-5(RNAi) embryo showing altered nuclear appearance (right). The timing of cell divisions in this embryo is also abnormal (only one of the cells has divided a second time) after the first embryonic division. Middle, a wild-type, two-cell-stage embryo (left) and a F55H2.3(RNAi) embryo (right) showing vertical rather than horizontal orientation of the spindle pole bodies in the right-hand cell.

Remote Antarctic island is 'richer in biodiversity than the Galapagos' Antarctica's remote South Georgia Island boasts 90 percent of the world's fur seals, half of the world's elephant seals, is navigated by vast populations of blue whales, sperm whales and killer whales, and has beaches that can be packed shoulder-to-shoulder with nesting penguins. In total, it contains nearly 1,500 recorded species, many of which are found nowhere else on Earth. It's difficult to believe that until recently, this biological treasure was believed to be nothing more than an "inhospitable lump of rock." In fact, researchers now believe that South Georgia Island contains more species than anywhere else in the Southern Ocean, and may be the most biologically diverse remote island in the world — even more diverse than the storied Galapagos Islands, according to the Independent. "It shows you don't have to be a tropical island or in a hot part of the world to support a lot of marine life.

MRI Lists of Nobel Prizes and Laureates Play MRI the Magnetic Miracle Game About the game In the MRI imaging technique, strong magnets and radio waves are used for getting images of inner organs made of soft tissue, compared to X-ray imaging where you get images of hard tissue, like bones and teeth. Read More » RNA interference Lentiviral delivery of designed shRNA's and the mechanism of RNA interference in mammalian cells. RNA interference (RNAi) is a biological process in which RNA molecules inhibit gene expression, typically by causing the destruction of specific mRNA molecules. Historically, it was known by other names, including co-suppression, post transcriptional gene silencing (PTGS), and quelling. Only after these apparently unrelated processes were fully understood did it become clear that they all described the RNAi phenomenon.
