Caenorhabditis elegans

Dauer Stage Development in C. elegans Yirui Chen Caenorhabditi elegans?has become an important organism in which to study processes that go awry in human diseases since over 50 yeas ago when Sydney Brenner had the foresight to develop the nematode (round worm)?Caenorhabditis elegans?as a genetic model for understanding questions of developmental biology and neurobiology. There are several attractive features that make Caenorhabditi elegans?an ideal organism for the study of gene regulation and function

Abstract The act of locomotion is highly dependent on the chemosensation of the worm, Caenorhabditis elegans (C. elegans). The use of chemotaxis enables the roundworm to distinguish various volatile and water-soluble chemicals that allow for growth and survival. We investigated the complex nervous system through the use of RNA interference (RNAi). By using RNAi, we were able to nullify certain protein expressions and test specific genes to observe their involvement in chemotaxis. The experiment

of three different strains of Caenorhabditis elegans using microscopy and a fluorescence microscope. The organisms contained fluorescence tags on the membranes of their synaptic vesicles to make it easier to see how the mutations affected the vesicles locations. Wild type C. elegans should be actively moving in an s-shape pattern under a microscope. Under a fluorescence microscope, the tags should appear at the nerve ring and along the nerve cords. In the C. elegans with a fusion defect, its movement

John Sulston. Their scientific discoveries have enhanced biological and medical research by allowing scientists to understand how these processes are regulated. In this essay I will explore Caenorhabditis elegans, cell lineage, and programmed cell death in which the article goes in depth with. II. C. elegans

Caenorhabditis elegans is a nematode worm that is used in a lab for research. This is because it enables researchers to use a simpler model of an organism without using humans themselves. The life cycle of a nematode worm is about three days (Hartwell 2011). It includes stages of the embryo, the L1 larva, L2 larva, L3 larva, the L4 larva, and the adult. The stages are the different molts and these are the growing of different cuticles and shedding the older ones (Hartwell 2011). This allows adaptation

I HAVE ABIDED BY THE UNCG Academic Integrity Policy ON THIS ASSIGNMENT. Student’s Signature Edmund Teba___________________________________ Date _05/02/2017 "I'm still turning over stones, hoping to find something new."(https://www.nobelprize.org/nobel_prizes/medicine/laureates/2006/mello-bio.html); this quote verbatim from Craig Mello speak to why I was drawn to him as my selection for Nobel Prize recipient. It is a definition of the quintessence of what we have been harping about all semester;

these diseases are facilitated by utilizing model organisms to study pathways involved in neurodegenerative diseases. One such model organism is the Caenorhabditis elegans nematode. The C. elegans roundworm has displayed usefulness as a template to study neurodegenerative diseases in humans, including Parkinson’s disease and Alzheimer’s disease. C. elegans has shown to be a useful model for the study of Alzheimer’s disease. Sydney Brenner first introduced the nematode as a model organism in 1963 (Brenner

‘Longevity Pathways converge on autophagy genes to regulate lifespan in Caenorhabditis elegans” Aging is the amount of changes in person overtime. It is a multidimensional process, which can affect a person physically and psychologically. With age, people weaken and affect their memory. There are four types of aging: intrinsic, universal, progressive and deleterious. Intrinsic aging is chronologic aging, it deals with internal factors, and it decreased fat cells size, and damaged fat cells differentiation

nematodes, Caenorhabditis elegans. Dr. Wightman’s experiment involved genetically analyzing a new sleep circuit in C. elegans. He initiated a discussion about a topic all college students can relate to: sleep. Animals (including humans) love to sleep, but why? Because it allows time for the brain to clear of any toxins, to produce new cells, and to consolidate new memories. Introducing his work, Dr. Wightman familiarized his audience about the glamorous and underappreciated C. elegans. The nematode
