    Is it okay to allow parents to pick and choose how their child should look, as if they are in Build-a Bear Workshop? Scientists in today’s modern world have made immense progress in the field of genetic engineering. Many have rightfully chided scientists and this new development of errant technology due to the unethical consequences that genetic alteration of children brings. One of those consequences is that a society gap will arise from the manipulation of an embryo’s genes. Additionally, a…

    1. In the article entitled, “The DNA Mystique: The Gene as a Cultural Icon,” authors Dorothy Nelkin and Susan Lindee argue that the gene has influence as a social symbol outside of its biological domain, becoming something like a “magical force”. Nelkin and Lindee describe the gene as, “powerful, deterministic, and central to an understanding of both everyday behavior and the “secret of life””. The popular media has helped to shape the general public’s view of the gene as an all powerful device…

    Nt1310 Unit 4 Lab 4

    • 367 Words
    • 2 Pages

    The first objective of Lab 4 is to use structure activity relationships to predict the properties of an acid and the potency of hallucinogenic compounds. The overall goal of the laboratory is to examine quantitative structure activity relationships (QSAR) in a system that is either chemical or biochemical. The lab is divided into two parts; predicting the acidity of an organic acid, and predicting the hallucinogenicity of derivatives of mescaline. The materials of this lab for both part 1 and…

    jail. DNA evidence can be unreliable and easily tampered with. DNA can become contaminated at a crime scene, or in a lab. This occurs when procedures are not followed correctly, or when the DNA is exposed to harsh conditions. Direct sunlight and moisture causes DNA to degrade, making it unusable. “When there are problems with DNA collection and analysis, the consequences can be severe. Mistakes can, and have, led to wrongful convictions.” A solution to this issue was to use “touch DNA”,…

    For as long as homo-sapiens have been on this earth finding sources of food had always been the number one priority. Humans, no matter the gender, spent most hours of each day hunting animals and foraging for edible plants and fruits. “That reliance on foraging characterized what historians and archaeologists call the Paleolithic era, or the “old stone age”.” (Jerry H. Bentley 7) During this time, and as the number of humans began to gather together forming a “community”, rules and regulations…

    The four forces of evolution are mutation, natural selection, genetic drift, and gene flow. Mutations are the only force that can change the genetic code and without them the other forces wouldn’t happen. When a mutation takes place in a sex cell, it can them be passed down through generations. Natural selection was first brought about by Charles Darwin. It is the belief that the better an organism adapts to their environment, the more likely they are to live longer as well as reproduce. Genetic…

    Chitosan is a natural linear amino polysaccharide gained from chitin which is, after cellulose, the second more common biopolymer on earth. Chitin is the primary component in the shells of crustaceans such as shrimp, crab, and lobster. Chitin is present in crayfish, insects, and vegetal species mainly in the walls of fungi. These species require nitrogen for nutritional cycle. Chitin has been sourced from different originate and its composition shown in table 2.1 (synowie). Small quantity of…

    The oldest forms of life are single-celled organisms known as microbes. There are many different types of microbes that are found all around the world, and they play an important role in the environment, in the body of animals, and even in the health of plants. The specific type of microbe investigated in this paper is the gram positive bacterium known as Kocuria rhizophila, which has a bright yellow color that simplifies identification. The main objectives of the paper are the following:…

    • 2 Pages

    Summary: Over the past two years, the bee population has decreased dramatically and has immensely affected the pollination of plants. The question they are trying to answer is are bees dying because of the Varroa mite and deformed wing virus or pesticides? The scientist’s hypothesis was that the sudden decrease of bees was because of the Varroa mite and deformed wing virus, not because of pesticides. Their experiment was to produce and infect the larvae, pupae, and fully developed bees with an…

    The article “Tweak in Gene Expression May Have Helped Humans Walk Upright” found on Science Daily discusses work conducted by researchers at the Stanford University School of Medicine and at the HudsonAlpha Institute for Biotechnology. These researchers have been able to distinguish what gave us humans the ability to walk upright through research conducted on the fish threespine stickleback. The fish has evolved multiple times over time in order to match different environments around the world.…
