The Genetic Modification of Human Embryos: The Negative Effects of an Unknown Process Imagine you are in the doctor’s office and you are told, “Congratulations for wanting a child! Now it is time to select your options.” You sit there with your spouse and decide the sex, hair and eye color, height, and DNA of your future child, just as you would customize a new car that you are buying. The issue is, however: what if you choose the wrong options, and when did nature disappear in the…

Many buildings around Iowa State Campus have very unique designs. Each design in each building have very deep meanings to understand the history and purpose of the building. One of the buildings that stood out was from an artist named Andrew Leicester who created the G-Nome on the Molecular Biology Building in 1992 and many other artifacts as part of the G-Nome Project. The G-Nome comes from two different words: Gnome (a dwarf-like creature that usually guards precious treasure) and genome (a…

Environmental-Dependent Sex Determination in Reptilians When we think of sex determination in organisms, we most often think of mitosis and the process of randomly receiving X and Y chromosomes from parent cells. This type of sex determination is known as genotypic sex determination (GSD), and it’s the most commonly found method of sex determination. However, this isn’t the only type of sex determination available to organisms. Some reptilians, for example, use environmental-dependent sex…

scientific discoveries have played an immense role in the emergence of the modern civilization .Many of the them have affected us and changed our lives. In the 1960s DNA was discovered and the event of that decade. It is a small part of nucleus in our cells of our bodies ,and consists of chromosomes which are the responsible aspects for determining the sex of and physical features of humans. For its wide characteristics, it is used in many sides of our lives such as medicine, security, and…

Asexual reproduction is a reproduction process with only one parent that ends with identical animal cells. The purpose of asexual reproduction is to reproduce with wasting less energy. Sexual reproduction is a reproduction process with two parents that ends up with unidentical animal cells. Sexual reproduction is used to reproduce and make a unique being. The animal I am focusing on is the red kangaroo. The red kangaroo uses sexual reproduction. This chosen type of reproduction is a good choice…

the function of a lysosome, enzymes that hydrolyze large molecules and then move the fragments on to other parts of the cell for other uses. Farber’s disease is a rare, genetic condition that involves a deficiency in the enzyme, ceramidase. Ceramidase is a lysosomal acid that causes cell growth, cellular differentiation, cell adhesion, the movement of cells and the death of cells. The body is unable to produce ceramidase with Farber’s disease, thus causing the buildup of ceramide. A gene is a…

There are several reasons why you might need a home paternity test. Perhaps the test is for a custody case or a child support hearing. Maybe you need the test because of adoption purposes. In any case, taking the test at home has several benefits. Below you will find a list of reasons why taking the test at home benefits you. The Benefits of Home Testing 1. Privacy. A paternity test is not anything that should make you feel ashamed or embarrassed. However, you still might want more privacy…

My Perception of Human Genetic Engineering In a world with constant technological and scientific breakthroughs, human genetic engineering is no longer a question of possibility, instead a question of when. As someone whose dream is to find a cure for cancer, I have always believed that the key to ridding the human body of diseases lies within human genetic engineering. Learning about current applications of genetic engineering in my school helped me realize how dependent we are on this…

With all of the technological and medical advancements over simply a few decades, scientists have been able to discover so many mysteries of the brain and how it functions. Even with all of these advancements in mind, many remain convinced that one's intelligence is tied to their DNA. People remain convinced that genius and genes go hand-in-hand. In Shenk's (2011) book, he delves into some of the misconceptions people have when it comes to intellectual capabilities. Shenk challenges people to…

a relic of pre biotic conditions or an artifact of the life process. One theory holds that when life appeared in the primordial soup, the first cell formed containing all L- amino acids. This would have been extremely improbable, however, if the soup were composed of an equal mixture of left and right enantiomers. Another possibility is that the first cell randomly formed with a slight excess of L-amino acids, and evolutionary selection favored life based on just one enantiomer. Some have…
