Senescence

1. In your own words, define what is a mutation? Abnormal inherited or acquired permeant alteration in the sequences of the nucleotides of the deoxyribonucleic acid of an organism may or may not change organism phenotype, it occurs with a frequency of less than1% among a population. 2. Are mutations bad or good for you? Justify your answer in either case Mutations could be good, bad, or may have little or no effect. Beneficial mutations: Some mutations if they happen they have a positive…

According to Eric Erikson, a German psychoanalyst, everyone must pass through a series of eight developmental stages throughout their lives. These stages are called psychosocial theory, which per Berger (20114) is, “A theory of human development that holds that irrational, unconscious drives and motives, often originating in childhood, underlie human behavior” (p. 23). According to Jean Piaget, a Swiss scientist, there are four stages that take place from birth to adulthood. These stages are…

getting shorter every time the cells divide. They stop telomeres from attaching to each other and stop losing genes from cell division. If chromosomes had no telomeres they would get shorter to the point where the cells cannot divide which makes them senescence (when cells remain viable but loose ability to divide) or make them die. Elizabeth Blackburn and Jack Szostak conducted an experiment which involved crossing boundaries between distance species. They did this after observing the…

Firestone, a radical feminist, attacked the idea of the “biological family” with a close eye on the idea that biological division of labor created through reproduction is the primary cause for male domination. Firestone’s arguments through her own book continued to be developed in the book Further Adventures of Dialect of Sex. This book is composed by multiple feminists who use theory to address several issues that pertain to women’s rights. The key debate that occurs in this book address, once…

Mr. Joyfellow felt 73.674 years old exactly to the third decimal place. Although he sometimes hated this number to the nearest tenth, today he hated it down to the thousandth, and would have even if the thousandth's place were zero. Disgusted by the necessary cliché of waking, he shuffled off to the kitchen as his stomach requested of him (rather impolitely, he thought). He had once been a man of regularity to the point of eccentricity, but that was less a trait of himself than of the past, and…

State of the Problem In its variety of forms, cancer is estimated to affect more than 14 million people per year, and is the cause the death of more than 8 million (National Cancer Institute). Despite millions of dollars of research in the field, and a concentrated effort by researchers around the globe, a panacea for cancer doesn’t exist, although much headway has been made in earlier detection and better treatment methods. Much of the difficulty in treating the disease lies in its diversity;…

If you know anything about modern genetics, then you should know that these nifty little segments of DNA, called genes, tell your body what to do and when to do it. For years scientist have been trying to figure out a way to manipulate these genes and modify them to achieve a desired effect in an organism, such as giving a mouse the ability to go longer periods without food, while eliminating the risk for undesirable mutations, like cancer. Genetically modified organisms such as mice have been…

The body is the primarily source of living. Living without a functional body gives us restraints on what we are capable of achieving on a daily basis. This leaves me to state that we must take care of the inputs and outputs of the body. If we don’t maintain a healthy lifestyle there can be many things that cause the body to break down and tremendously cause pain, hurt, and dissatisfaction overall in or lives. Proper fueling of the body requires getting adequate amount of sleep, eating nutritious…

Introducing Genes from other Organisms to Improve Efficiency Besides using just genes from the plant itself, scientists have been able to introduce other genes from other organisms into the plant cells, one of the first being (Fructose-1, 6-Sedoheptulose-1, 7-biphosphate). The (Fructose-1, 6-Sedoheptulose-1, 7-biphosphate) gene comes from cyanobacteria and was introduced to a transgenic tobacco plant. Once again, through the use of overexpression, the tobacco plant showed an increased…

Interview Project Sitting in the kitchen on a rainy day while Chris Bonner sits across the kitchen island, dressed in a sweatshirt and shorts, wearing his Colorado golf cap, playing Clash of Clans on his I-pad. A forty-eight-year-old male, although claiming to be thirty-one in regard to his heart transplant a year ago appears healthy and willing to partake in this interview. Born to Kathy and William Bonner on May 25 1968. Chris grew up in Woodstock, Illinois, where his mother (from a family of…
