Essays on Genetics

Mitosis is a process of cell duplication, or reproduction, where one during this process gives growth to two identical daughter cells; however, there is no crossing over. Mitosis is asexual and has 1 division of the nucleus in cytokinesis (Simon, Reece, & Dickey, 2010). Meiosis …

Introduction Each individual is marked by unique genetic sequences embedded in strands of DNA (deoxyribonucleic acid), except for identical twins. Surprisingly, DNA source can easily be obtained from single white blood cell, cheek epithelial cell contained in the saliva on cigarette butt or chewing gum, …

Abstraction The intent of this probe is to find the frequence of meiotic divisions analyzed from intercrossed crossings collected from different strains of the fungus Sordaria fimicola. The experiment was conducted to show intercrossed crossings with MI and MII forms of ascospores within the asci. …

It is not commonly known that the brain is 90% developed by age five. Most people believe that at age five children are just starting to learn. In fact, the brain absorbs more from birth to age five rather than from age five on. Parents …

Organelles can contribute or cause a disease like Cystic Fibrosis. First the organelle itself may be defective because its molecules do not function well or because there has been damage to it by exposure to some harmful substance such as a chemical. Within the endoplasmic …

The discussion is formulated, as the entire thesis, along with the two major investigations done during this study. These are the study of the regulatory mechanism of wg genes expression in the first part and of Rem expression in the second part. An emphasis is …

It can be difficult to understand and realize what determines our destiny. There are Contradiction determining if our characteristics and behavior are primarily due to Genetics or the environment in which we live. Many factors and aspects of Lives influence us daily. These factors create …

Multiple situations and conditions can impair or influence human behavior in individuals. My hypothesis was genetics has the strongest influence on human behavior because of the inability to have control over heredity. Without control, how can one improve or change their behavior? Mental disorders can …

Abstract Sexual reproduction in organisms is a cause for genetic variation. This can be seen through the process of meiosis in Sordaria fimicola because of the effects of crossing over and independent assortment that occur in meiosis I. Before performing this experiment we hypothesized that …

My name is Erwin Chargaff and I discovered the structure of DNA. After reading Oswald Avery’s report, in 1944, about how genes were composed of DNA I become motivated to begin work on the chemistry of nucleic acids. I started researching with the belief that …

Genetic testing has become an extraordinary tool in the fight against breast cancer in young women. Due to advancement of scientific research, the identification of the genetic markers of disease through the collection and analysis of an individual DNA is possible today. Genetic testing can …

Genetically modified foods (GMF) have foreign genes such as plants, animals and bacteria inserted into their genetic codes. Genetically modified organism is processed in a way that does not occur naturally. Combining genes from different organisms is known as recombinant DNA technology. There are alternative …

Diseases can come from a variety of places – bacteria, viruses, and parasites to name a few, all which can affect metabolic rates in animals. Khokhlova etal, conducted an experiment where they infected indiviudal gerbils (Gerbillus dasyurus) with 50 fleas (Xenopsylla ramesis) per gerbil, and …

Genetically modified organisms- a step ahead or a step in the wrong direction? Paulina Langowska Genetically modified organisms, also known as GMO, are such organisms whose genetic material has been artificially changed using genetic engineering. Genetic engineering, to put it simply, is altering the DNA …

DNA, RNA, PROTEINS STARTS WITH ? Name _______________________________ DNA that is spread out in the nucleus of a non-dividing cell so it can be read is called _C_ __ __ __ __ __ __ __ __ . The group of 3 nitrogen bases in the …

Autosomal Inheritance of Wrinkled and black Mutations in Drosophila melanogaster Abstract Homozygous Wrinkled virgin females and homozygous black male Drosophila melanogaster, were crossed. Mutations were located on chromosomes two and three respectively. The F1 generation, all Wrinkled and black, was inbred yielding and F2 generation. …

Protein misfolding can be an aspect of several different human disorders, including cystic fibrosis, Alzheimer’s disease, and atherosclerosis. Many times, the misfolded protein is a membrane protein. In fact, a type of diabetes insipidus results from a mutation in the G-protein-coupled vasopressin 2 receptor that …

Annie Murphy Paul’s article `Kid stuff: Do parents really matter?` outlines the findings of a highly controversial study on the role of nature and nurture in children’s education. The article states that a group of researchers from George Washington University and the Institute of Psychiatry …

Genes contain information that determine everything from appearance to intelligence. A person inherits genes from their parents, and how parents live affects their children's genes. It’s a mistaken assumption that everything you inherited in your genes is permanent. Your lifestyle and circumstances can awaken individual genes and/or suppress others. Here …

DNA contains genetic material and information that makes up each individual trait. Every person can be identified by providing his or her genetic information based on a particular DNA strand. DNA information is an effective way of identifying persons if it is used properly. It …

In this article, I am to create a whole new version of Frankenstein from the old version made by Shelley. Dr. Baltus Crane is a genius genetic doctor; he is a member of the genetic scientists who makes researches about developing human clones. It was …

This project presents the design methodology of wireless fingerprint management system for easy and time saving attendance. The project is used for the attendance of students at Institution. Since the project is wireless it is portable. As the student impress their fingerprint against the scanner …

Introduction Histone Proteins are favourably the alkaline proteins which are present in the nucleus of the eukaryotic cell. They are the basic parts responsible for wrapping and organizing DNA into chromosomes in the nucleus. They are the principal protein elements of the chromatin and acts …

Uncontrolled transposition is deleterious to the cell and thus, the frequency of transposition is generally kept to a minimum by various regulatory mechanisms. Describe the FOUR ways that transposition is controlled. Transposition is the movement of a particular fragment of DNA from one part of …

The term “genetic engineering” was first coined by Jack Williamson in is science fiction novel Dragon’s Island, published in 1 951 ,one year before Dona’s role in heredity was confirmed by Alfred Hershey and Martha Chase, and two years before James Watson and Francis Crick …

Denaturing Gradient Gel Electrophoresis (DGGE) is a robust process by which point mutation can be detected. It depends upon polymerase chain reaction (PCR) products which denature at different temperatures depending upon if they contain homoduplex or different products from both wild type and mutated genes …

DNA is a nucleic acid that is basis of genetic information. It is like a set of instructions for our bodies and genetic codes. DNA has many different components that make it up such as hydrogen, oxygen, nitrogen, and phospurous. The structure has two long …

One of the primary needs of man, in terms of the cognitive and psychological aspects of life, is to understand himself and other forms of life in order to determine each other’s role and place as inhabitants on earth with unique physiological, anatomical, and most …

In this paper I will be studying chromosome 11 of the human genome. Specifically, I will be researching some of the diseases that occur when there are mutations in the genes on chromosome 11. Five specific diseases will be looked at and studied in detail: …
