genes



Genes are the smallest units of heredity. The information from all the genes, taken
together, makes up the blueprint or plan for the human body and its functions. A gene is a
short segment of DNA which is interpreted by the body as a plan or template for building a
specific protein. Genes reside within long strands of DNA which in turn make up the
chromosomes. Some diseases, such as sickle cell anemia, can be caused by a change in a
single gene (one out of the millions of genes which make up the plan for the entire human
body).


Genes are arranged in order along the DNA strand within the chromosome (similar to beads
on a string). Matching genes from each parent exist on matching chromosomes and matching
positions along the DNA within the chromosome. These genes are paired, one from the mother
and one from the father. Genes are described as DOMINANT or RECESSIVE. DOMINANT means that
one gene in the gene pair is able to control the trait which that gene pair codes for.
RECESSIVE means that both genes in the gene pair are necessary to control the trait.

    cholesterol For years, cholesterol has been a major concern for millions of people around the world. This fear of cholesterol has led to many consultations with specialists like physicians and nutritionists. It seems that there is a great misconception about this molecule. A majority of the population is conscious of the harm that it can cause, but they are not aware that it has pertinent values to our body. There are two major forms that cholesterol comes in: 1) low density lipoprotein, which i

    None Provided1 Vision and Movement When we discuss our brain, we usually focus on the brains ability to think. That task alone is extremely complex and involved, but the brain also has many other tasks. Most of the time the brain is on autopilot, meaning that most of the activities preformed are just automatic. Our five senses; sight, sound, touch, taste, and smell, are automatically preformed in our brains. We don\'t have to think about how something sounds, we just hear it and we then interpre
  • Schizophrenia
    Schizophrenia Schizophrenia Josh Schizophrenia is a debilitating mental disorder characterized by a dysfunctional thinking process and withdrawal from the outside world. The word schizophrenia comes from two Greek words schizo which means split and phrenia, which means mind. This doesnt mean that a person with the disorder has multiple personalities, but rather parts of the mind seem to be operating independent of each other. The disease affects approximately 1 in 100 people and there are thoug

    The Human Genome Project Human Genome Project, international scientific collaboration, the goal of which is to gain a basic understanding of the entire genetic content, or genome, of a human being (see Genetics; Heredity). This genetic information is found in each cell of the body, encoded in the chemical deoxyribonucleic acid (DNA). The project is intended to identify all the genes in the nucleus of a human cell; to establish, by a process known as mapping, where those genes are located on the

    D Caries Introduction Caries have been a constant nuisance to humans, decaying teeth can become a major problem for those affected. It is certainly not the oldest pathology, nor the one of the greatest prevalence throughout humankind, but the information that can be extrapolate from such pathologies is great. The aim of this paper is to outline the pathology of caries and the influence that these have had on the human populations affected. Caries or caries dentium is the common name for tooth de
  • Human Sexuality
    Human Sexuality Study of Human Sexual Behavior Human sexual behavior is just one of the many things anthropologist study when it comes to humans. Humans are highly complex and social beings. We often wonder why we do the things we do. Why do some people cheat, while others stay monogamous? Behavior is not an easy thing to study because it is subject to change and is continuously changing. There is no clear-cut reason for human behaviors, unlike mammals, humans can reject or override genetics. We

Introduction Science is a creature that continues to evolve at a much higher rate than the beings that gave it birth. The transformation time from tree-shrew, to ape, to human far exceeds the time from an analytical engine, to a calculator, to a computer. However, science, in the past, has always remained distant. It has allowed for advances in production, transportation, and even entertainment, but n

  • In Support of Human Cloning
    In Support of Human Cloning Human cloning is inevitable. As part of the progress of science, human cloning will take place regardless of who opposes it. In this paper I will explain what human cloning is, some of the ethical and moral objections to it, some medical benefits it could serve, what many different religions think of cloning humans, and ultimately why I feel that this would be beneficial to our society. In order to understand the objections and the potential of human cloning, one must
  • Plant Cloning
    Plant Cloning Cloning is asexual reproduction. Cuttings are taken from a mother plant in vegatative growth, and rooted in hydroponic medium to be grown as a separate plant. The offspring will be plants that are identical to the parent plant. Cloning preserves the character of your favorite plant. Cloning can make an ocean of green out of a single plant, so it is a powerful tool for growing large crops, and will fill a closet quickly with your favorite genetics. When you find the plant you want t
  • To clone or not clone
    To clone or not clone To clone or not to clone Cloning humans has recently become a possibility that seems much more feasible in today\'s society than it was twenty years ago. It is a method that involves the production of a group of identical cells or organisms that all derive from a single individual (Grolier 220). It is not known when or how cloning humans really became a possibility, but it is known that there are two possible ways that we can clone humans. The first way involves splitting a

    sexual orientation Sexual orientation has been and to some degree is still seen as a taboo topic. For many years it has been argued that sexual orientation is based on one\'s gender and one\'s sexual preference, should be based on one\'s sex (i.e. females should be attracted to males and males to females). For generations, these narrow views were considered to be the norm. However, hidden within society was a lifestyle that once aired was seen as deviant. Homosexuality and many sexual orientatio

Investigators soon learned that dopamine by itself was useless; it would be metabolized before reaching the brain. So, in 1970, levodopa w

    cloning The biological definition of a clone is an organism that has the same genetic information as another organism or organisms ("Cloning", 1997). From this definition and from information about the science behind cloning, my current view on cloning is that it is ethical. This statement ignores information about how we can misuse cloning and what consequences occur when the procedure is unsuccessful. I currently do not think cloning should be used until it is perfected. I doubt however that

This fact is very cleverly illustrated by Raphael\'s "School of Athens" (1510-11; Stanza della Segnatura, Vatican), where Plato is portrayed looking up to the higher forms; and Aristotle is pointing down because he supports the natural sciences. In a discussion of politics, the stand point of each philosopher becomes an essential factor. It is not coincidental that Plato s

It affects the way you eat and sleep, the way you feel about yourself, and the way you think about things. A depressive disorder is not the same as a passing blue mood. It is not a sign of personal weakness or a condition that can be willed or wished away. People with a depressive illness cannot merely "pull themselves together" and get better.
