  • Recent Developments In Research On The Genetics Of Human Sexual Orientation

    1532 words, 7 pages

    Human sexual orientation has been a controversy with a high tendency for debate. Lesbians, gays, supporters, and their friends are in a heated dispute about the origins of sexual orientation. There are many possibilities, spanning from personal lifestyle choices, environmental factors, to genetic heredity. In the past few years it has become increasingly popular to examine homosexuals, in hopes of determining the basis for a lifestyle involving same sex relationships. Henry Havelock Ellis first addressed inquiries on the basis of homosexuality over a c

    Commercialisation Of Genetic Sequencing

    2257 words, 10 pages

    This essay is an exploration of the commercialisation of genetic sequencing. The history of this technology will be presented in the context of the model demonstrated by Vijay K Jolly, 1997. In this model, Jolly identifies five processes essential in the commercialisation of new technologies; imagining, incubating, demonstrating, promoting and sustaining (Jolly, 1997). This submission is the first of two parts and will cover the first three phases of the Jolly model, referring also to the sub processes identified by Jolly as bridges between each phase (Jolly, 1997). The basic definition

    Evolution

    1670 words, 7 pages

    A Lesson in Evolution Evolution is the name of a theory that explains change in living organisms and variation within species. Evolution is a process in which the characteristics of living organisms change over many generations while traits are passed on from one generation to the next. Charles Darwin, who is considered the father of evolution, discovered the origin of the species and the process of ongoing history of life on earth (Perry, 2006). Long before the rise of modern science in Western Europe in the 17th and 18th centuries, a powerful view had come about that God created every orga

    Homosexuality: A Product Of Nature Or A Product Of Nurture

    1365 words, 6 pages

    The theory on whether homosexuality is based on the influences of nature as opposed to the influences of nurture has encompassed the study of psychology and biology for hundreds of years. Zachary Broome, member of the Blount Undergraduate Initiative of the University of Alabama discusses this idea in his article, “The Legal Issues of Genetic Discrimination.” He debates that both sides contribute to the overall establishment of sexual orientation in a human being yet the main reason for even studying this topic is to determine its effect on legal issues(Broome, 40). Broome discusses previous s

    It has often been suggested that genes have an influence on human aggression. Twin and adoption studies have often been used to determine the influence an individual’s genetic makeup has over aggressive behaviour. For example, Rhee and Waldman conducted a meta-analysis of twin and adoption studies on antisocial behaviour. They found that identical twins (share 100% genes) were more similar in anti-social behaviour than fraternal twins (50% share). This supports the theory that genetics influence aggressive behaviour, even allowing for the more closely similar environme

    Intron And Exons

    1009 words, 5 pages

    Why does DNA have introns and exons and what is the function of junk DNA? DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA). An important property of DNA is that it can replicate, or make copies of itself. Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases. This is critical when cells divide because each new cell needs to have an exact copy of th

    Creationism Vs Evolutionism

    1014 words, 5 pages

    Evolutionism and creationism both are a widely talked about controversial issue. Today many people believe in one because they do not know anything about the other or they refuse to learn about the other belief. So many people say why either evolutionism or creationism is real with no actually facts, only opinions. Both of the parties have numerous theories, they try to release a theory so many others can follow their belief with them. Neither belief systems have been able to prove a completely factual theory hence why they are only theories. Evolutionism was thoug

    William Pan Contrary to popular belief, it was the Swiss chemist Friedrich Miescher that had first identified hence discovered the molecule of DNA inside the nuclei of some human white blood cells: James Watson and Francis Crick only aggregated the knowledge in the scientific realm in a scientific paper and won Nobel Prizes for it; both of whom are widely regarded as the forefront of DNA’s discovery. This mirrors the common misconception that Thomas Edison invented the light bulb which in reality is only partially accurate. DNA discovery and brief Bio Friedrich Miescher was born in the ci

    Human Genome Background And History

    1260 words, 6 pages

    The idea of the HGP was initiated in 1977, when simple and efficient methods for sequencing DNA were described. Before that time the possibility of sequencing the entire human genome was no more than extreme wishful thinking. In the 1980's it was becoming increasingly apparent to many scientists that an understanding of basic biology would be greatly enhanced if the detailed structure of DNA was understood. Over the last two decades, automated DNA sequencers have made the process of obtaining the base-by-base sequence of DNA easier. In 1984, for the first time a meeting was sponsored by the De

    Growth Growth is a process everything goes through, from animals to vegetables to the human body. Throughout different life stages the human body grows physically over the years. Growth starts from being a baby to a child to adolescence through to adulthood; the body goes through all sorts of different body sizes and changes in appearances. A person’s growth depends on the environment they live in and genetics can also determine the pace of growth. Diet and nutrition are important factors the body requires to grow. Growth involves the change of a beings height, size and shape. Body organs al

    Mendel Law Of Inheritance

    1497 words, 6 pages

    Mendel discovered that when crossing purebred white flower and purple flower plants, the result is not a blend. Rather than being a mix of the two, the offspring was purple-flowered. He then conceived the idea of heredity units, which he called "factors", one of which is a recessive characteristic and the other dominant. Mendel said that factors, later called genes, normally occur in pairs in ordinary body cells, yet segregate during the formation of sex cells. Each member of the pair becomes part of the separate sex cell. The dominant gene, such as the purple flower in Mendel's plants, will h

    Nature Vs Nurture: Inherited Genes Or Environmental Influences Affecting Our Personality

    1500 words, 6 pages

    The nature versus nurture debate is a big controversy concerning whether inherited genes or environmental influences affect our personality, development, behavior, intelligence and ability (Nature versus Nurture, 2013). The argument of nature and nurture has been going on for years, and scientists are still struggling to find out why we are the way we are. Some scientists believe that it is strictly genes that make one person different from another. One example is the story of Jim Lewis and Jim Springer who are twins and were separated at birth. They first met on February 9, 1979, after 39

    How Did The Work Of Other Scientists Help Crick And Watson To Develop Their Theory For The Structure Of Dna

    1763 words, 8 pages

    DNA was first actually discovered in 1869 by Friedrich Miescher, only later followed by the theory of the structure. The structure of DNA is built up from base pairings, deoxyribose sugars, and phosphate molecules. However, a nucleotide is formed from a phosphate joined to a deoxyribose sugar, which is then bonded to a single organic base. Nucleotide is joined to another nucleotide by both the base pair and the phosphate end. The two nucleotide strands that make up DNA run in opposite directions, one runs from 3’ to 5’ and the other runs from 5’ to 3’. The 5’ end
