Discussion: This experiment was designed to understand how manipulating protein expression would change C. elegans’ level of chemo sensation. Based on the data generated from our individual data and the class data, the data did not match the theoretical numbers. Only our individual syd-1 data was able to exactly match with the theoretical chemotaxis index. There are many potential reasons why the worms did not move towards the diacetyl, however, it was surprising how syd-1expressed such a…

-Cas9 than there is cons. There is many pros to C.R.I.S.P.R.-Cas9. It is capable of curing some diseases in monkeys and mice at the moment. In the future, it may be used on the human species. Cas9 detects the viral DNA and destroys it. Cas9 is also used to remove DNA of an integrated HIV virus from an infected human cell. C.R.I.S.P.R. allows bacteria to be taken out of the viruses and become healthy again. This also allows all cells in an organism to recognize the viruses they have been…

One great organism to study is Caenorhabditis elegans (C.elegans ) because it is hermaphrodites, transparents and small enough to observe under the microscope. After adding mutagens to them, scientists can get all kinds of freak worms after few days. “Bag of worms” are one of them. It can not lay eggs so its body occupied with dozens of eggs. When eggs hatched inside the worm, larvae eat the mother worm and them come out. Ambros, a scientists who just finished doctor degree at MIT, first…

Bacteriophages (phages) are viruses that exclusively infect and replicate within bacterial cells. Phages are ubiquitous, with an estimated 1x106 particles per drop of seawater and as many as 1x108 particles per g of soil. Phage predation destroys an estimated one-half of the bacterial population worldwide every 48 h, hence regulating the population dynamics of natural bacteria (Deresinski 2008). Bacteriophages attach to their host cell by specialized structures called tail fibers, inject their…

editing of the genome has been achieved and advanced through the development of sequence-specific nucleases1. Zinc-finger nucleases and transcription activator-like effector nucleases (TALENs) are programmable DNA binding nucleases previously used to achieve this targeted editing of DNA. However these tools have been found to be both time consuming and difficult to employ. The development a system known as CRISPR/Cas9 system brings both ease and efficiency to world of targeted genome editing.…

all are maintained as pure-bred stocks through selective breeding, which aims to maintain a closed genetic lineage. Most of the dog traits follow simple genetic rules. Traits from dogs are often referred to as being dominant or recessive. Just like humans, dogs have two copies of one gene (one which came from the mother…

Eukaryotic organism such as drosophila have been used extensively to demonstrate the classical Mendelian laws because they are inexpensive and abundant in genetic variations due to a small number of chromosomes. The purpose of this lab was to determine the phenotypic ratio for monohybrid and dihybrid crosses using drosophila. In a monohybrid cross, a single trait (eye color) is crossed in the organism and in a dihybrid cross,two different traits (eye color and wings) are crossed for a…

Introduction Caenorhabditis elegans is a common organism that is used in many experiments due to its easy upkeep, low cost, short life cycle, fast reproduction, large reproduction size, and genetic manipulability with transparent body structure (Maxwell C. K. Leung, Phillip L. Williams, et al.). The use of C. elegans has allowed many discoveries to be made throughout history. One experimental technique that enhances their use is a green fluorescence protein (GFP), this allows different regions…

factors. Nurture is mostly taken from the effect of outside factors after opening the product of contact, knowledge and education of an individual. The nature-nurture debate is concerned with the relative contribution that both influences make to human behavior. The certain physical characteristics are biologically determined by genetic legacy. The color of eyes, straight or curly hair, color of the skin and certain diseases are all a role of the genes we receive. In men the “Height, weight,…

the genomes of chimpanzees and humans. Pollard’s goal was to understand the sequences of DNA bases and letters in the genome as well as the understanding of how the human genome was evolved through years. Pollard had begun on finding DNA sequences that set chimps and humans apart after having some evidence she revealed that human DNA blueprints are 99 percent identical to our closest living relative chimpanzees. Furthermore, she discovered that the three billion letters that made up the human…
