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…

are both prokaryotes, without any complex cell structure. When looking through a microscope they are both identical in appearance to include shape and size. They both reproduce using binary fission, and move around using flagella. Archaea and bacteria have cell walls on the outside, which provide support, and lets Archaea and bacteria are both prokaryotes, meaning they do not have a nucleus and lack membrane-bound organelles. They are tiny, single-cell organisms called microbes, which cannot…

In the world of Andrew Niccol’s film Gattaca, tinkering with human genetics has become the norm in the search for perfection of body and mind. The practice has become so widespread that those conceived naturally suffer discrimination on the basis of their DNA which in turn creates a class divide between the two groups. In the film genetics, and the imperfection drawn from them is overcome by means of raw determination by the protagonist and these concepts are explored through a variety of…

Animal Testing Animals have been the key point in animal testing. However, the amounts of animals being use are suffering during the process of being experimenting on. People don’t realize that animals are living being that has feeling and emotions just like humans do. People do not understand the nature that goes around them. They choose to be ignorant and avaricious about money and wasting animal lives because they feel that animal pain is less important than human pain. Animal…

Since the days of the Nazi regime and the blonde hair – blue eyes craze, society has had highly specific standards of what is “perfect” and what is not. The human race is going to great lengths to become perfect beings, even when there are known complications involved, such as plastic surgery that can cause undesired facial deconstruction later on in life. Pre-implementation Genetic Diagnosis (PGD) is just another one of these procedures where perfection can be achieved. Parents are using PGD to…
