Family And Friends Sexual Orientation
1,357 wordsSexual 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 orientations were seen as sexua...

The smooth endoplasmic reticulum of skeletal muscle stores calcium ions that function in muscle contraction. The Golgi apparatus is composed of flattened membranous sacs, containing cisternae, that are stacked on each other like dinner plates. The Golgi apparatus modifies, packages, and distributes proteins and lipids manufactured by the rough and smooth endoplasmic ret...

Percent Of The Cases Genetic Disorders
1,268 wordsDown syndrome, the most common genetic birth defect associated with mental retardation, occurs equally across all races and levels of society. The effects of the disorder on physical and mental development are severe and are expressed throughout the life span. The individual's family is also affected emotionally, economically, and socially (Bellenir 1996). Characteristics associated with Down syndrome include: epicanthus folds, unilateral squints, a flat saddle nose, flat jaw bones, large fissur...

Nitrogenous Bases Amino Acids
999 wordsDeoxyribonucleic acid and ribonucleic acid are two chemical substances involved in transmitting genetic information from parent to offspring. It was known early into the 20 th century that chromosomes, the genetic material of cells, contained DNA. In 1944, Oswald T. Avery, Colin M. MacLeod, and Maclyn McCarty concluded that DNA was the basic genetic component of chromosomes. Later, RNA would be proven to regulate protein synthesis. DNA is the genetic material found in most viruses and in all cel...

Spindle Fibers Asexual Reproduction
512 wordsCellular Reproduction is the process by which all living things produce new organisms similar or identical to themselves. This has to happen because if a species were not able to reproduce, that species would quickly become extinct. Reproduction consists of a basic pattern: the conversion by a parent organism of raw materials into offspring or cells that will later develop into offspring. The reproductive process, whether asexual or sexual always involves an exchange in hereditary material from ...

History Of The Human Genome Project
1,354 wordsThe Human Genome Project (HGP) is an international research effort to decipher the entire human genome and understand the unique hereditary instructions that each person possesses. The HGP is a jointly funded project by the U. S. Department of Energy (DOE) and the National Institutes of Health (NIH) with additional research done by the National (NHGRI). The project, launched in 1990, was originally planned to last 15 years, but rapid advances in technology have accelerated the expected completio...

In 1838 a botanist called Schleiden derived the theory The basic unit of structure and function of all living organisms is the cell. Over 150 years later this can be regarded as one of the most familiar and important facts within the bio...

Of these chromosomes, those that determine sex are X and Y. Females have XX and males have XY. In addition to the information on sex, the X chromosomes carry determinants for a number of other features of the body including the levels of factor VIII and factor IX. 1 I...

Spindle Fibers Cell Membrane
592 wordsThe life Process of a cell In my report you will learn about the life process of a cell based on the two main functions, metabolism and mitosis. You will learn about the four stages of metabolism: ingestion, digestion, respiration, and excretion, and how the cell completes them. You also will acquire information about the four stages of mitosis: prophase, metaphase, anaphase, and telephone, and how the cell completes them. Mitosis is the process in which cells reproduce. These two processes are ...

Children With Down Syndrome People With Down Syndrome
1,767 wordsDown Down Syndrome Down Syndrome Down syndrome is a combination of birth defects including some degree of mental retardation and characteristic facial features. It is also called trisomy 21. Down syndrome occurs when there is an abnormality in chromosome 21. It is found in approximately 1 out of 1000 all live births. Each year, 3, 000 to 5, 000 people are diagnosed with Down syndrome in the United States. The formal story began in 1866, when a physician named John Langdon Down first described a ...

They have deciphered the code, DNA, by which animals and plants pass on their characteristics to their offspring. They have even leant how to alter that code to produce life forms with new characteristics. This new technology involving both chemical and biological science is known as genetic engineering. Through this new technology, we shall soon be able to prov...

Gene Therapy Germ Cells
1,087 wordsHow does gene therapy work? All life contains genetic information in the form of DNA. DNA can be reproduced and passed on to subsequent generations. A gene is a stretch of DNA that contains the blueprint for the sequence of amino acids making up a particular protein. Proteins are vital because they are used in catalyzing various biochemical reactions, they act as messengers, they regulate cell growth, development and reproduction, transport oxygen in the blood and are a defense against diseases....

Mary Shelleys Frankenstein Cloning Of Humans
1,951 wordsThe process of cloning is the process of using the genes of a being to create another being genetically identical to it. Cloning technology has been called the forbidden fruit of biology (Begley 54). For years, scientists have been trying to perfect the cloning technique. In Scotland, scientists at the Roslin Institute have finally succeeded. Their success comes in the form of a Finn Dorset ewe named Dolly. Dolly is a clone. Now that the cloning of mammals from body cells has been accomplished, ...

Ovarian Cancer Oral Contraceptives
4,183 wordsOf all gynecologic malignancies, ovarian cancer continues to have the highest mortality and is the most difficult to diagnose. In the United States female population, ovarian cancer ranks fifth in absolute mortality among cancer related deaths (13, 000 /yr). In most reported cases, ovarian cancer, when first diagnosed is in stages III or IV in about 60 to 70 % of patients which further complicates treatment of the disease (Barber, 3). Early detection in ovarian cancer is hampered by the lack of ...

1,572 wordsMitosis in cancerous cells Mitosis, the process in which a cell undergoes nuclear division, is one of the four subdivisions of the cell cycle responsible for cell growth and reproduction. The first step in mitosis is prophase. In prophase the chromatin, diffuse in interphase, condenses into chromosomes. Each chromosome duplicates and has become two sister chromatids. At the end of prophase, the nuclear envelope breaks down into vesicles. The following step in mitosis is metaphase. During metapha...
