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…

Although the research showed that rats and human genomes were were not identical to rat genomes, “however, they also found that the rat genome contains about the same number of genes as the human ...genomes. Furthermore, almost all human genes known to be associated with diseases have counterparts in the rat genome and appear highly conserved through mammalian evolution, confirming that the rat is an excellent model for many areas…

Bacteria. 2. What do you think are the implications of studying these organisms in comparison to human DNA? What knowledge might we gain about ourselves from them? There are many genes that are similar and have the same functions, studied by the genome sequence. So to differentiate between the two would be difficult. 3. Which gene is present in every living thing, what does it do? EEF1 ALPHA1; tells cells how to read the instructions encoded in other…

and discrimination is based on genes. Vincent undergoes dramatic measures in order to reach his goal of one day being sent off to space. He masquerades as Jerome Marrow; a supposedly genetic superior that possessed all of the components of the best genomes. However, as the movie continued to unfold the issues of genetic discrimination, genetic modification, and advancement of technology that associates itself into genetic testing were the some of the main issues that occurred throughout the…

When considering ethics, we must evaluate the difference between what we can do and what we should do. There is no clear cut, definite solution when considering whether or not parents should be able to alter the genome of their children and in which ways altering is considered ethical. With the utilitarian concept, there is no right answer, there is only the idea of the “best answer,” which includes the many complex contradictions between each side of the controversy…

DNA” tells the beginning of gene editing. It all starts with Japanese scientist noticing unusual repeated DNA sequences. This later helped scientist to realize that DNA could be edited. Within this article it talks about different discoveries about genome editing and also has an educational image of Crispr editing. This article answers the questions of what is gene editing, what it might treat and the biggest hurdle. Also the ethnic controversy, if it is legal and its possibility beyond…

The video “Public Genome” demonstrate an interesting perspective about how our genes play a vital role in our predisposition for certain diseases such as Alzheimer or cancer. Fragments of the six billion letters in our DNA are what makes up a gene found on our chromosome. In humans, these 20,000 plus genes transcribes to form a mature mRNA which then gets translated in the ribosome to produce a particular protein like collagen for our skin or hemoglobin in our red blood cells. Although knowing…

Should Genetic Engineering be used to add Intelligence Genes to Humans? If you have the ability to design your own child, what kind of genes would you add? Would it be genes associated with attractive physical appearance, strong immunity, or great intelligence? In the article Future Humans: Four Ways We May, or May Not, Evolve, James Owen gives four predictions regarding the future of humanity, one of which predicts that in the future, the path of artificial selection would be directed by…

The Epigenetics Revolution: How Modern Biology Is Rewriting Our Understanding of Genetics, Disease, and Inheritance, written by Nessa Carey, is a uniquely constructed introduction to the world of epigenetics. Regardless of its recent emergence in science, Carey articulately ties in both historical context and scientific evidence to outline and support the developing knowledge of epigenetics. She uses scientific studies, advances, and even possible future developments of the field to engage and…
