DNA replication – Wikipedia

Posted: Published on December 5th, 2016

In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. This process occurs in all living organisms and is the basis for biological inheritance. DNA is made up of a double helix of two complementary strands. During replication, these strands are separated. Each strand of the original DNA molecule then serves as a template for the production of its counterpart, a process referred to as semiconservative replication. Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication.[1][2] In a cell, DNA replication begins at specific locations, or origins of replication, in the genome.[3] Unwinding of DNA at the origin and synthesis of new strands results in replication forks growing bi-directionally from the origin. A number of proteins are associated with the replication fork to help in the initiation and continuation of DNA synthesis. Most prominently, DNA polymerase synthesizes the new strands by adding nucleotides that complement each (template) strand. DNA replication occurs during the S-stage of interphase. DNA replication can also be performed in vitro (artificially, outside a cell). DNA polymerases isolated from cells and artificial DNA primers can be used to initiate DNA synthesis at known … Continue reading →

Title Length Color Rating The Effects of Genetic Engineering on Agriculture - Genetic engineering is a way in which specific genes for an animal or plant can be extracted, and reproduced to form a new animal or plant. These new organisms will express the required trait for that gene. This practice is a very controversial topic within the scientific world. It is being implemented in various areas such as agriculture even though there are many alternatives that can be found for genetic engineered crops, such as organic materials and reducing leeching of the soil. The controversy regarding this practice occurs as it is believed to contribute both negative and positive implications and dangers, not only to oneself but the environment as a whole.... [tags: Genetic Engineering ] :: 5 Works Cited 1303 words (3.7 pages) Strong Essays [preview] Pros and Cons of Genetic Engineering - Genetic Engineering is highly controversial since some people believe that genetic engineering is playing God. As this fact there is opposition to the progression of the field by people who do not see the value in genetic engineering, or they fear what genetic engineering may lead to for us as people. There is a history … Continue reading →

Gene Therapy Technology Explanied

Posted: Published on December 3rd, 2016

Virtually all cells in the human body contain genes, making them potential targets for gene therapy. However, these cells can be divided into two major categories: somatic cells (most cells of the body) or cells of the germline (eggs or sperm). In theory it is possible to transform either somatic cells or germ cells. Gene therapy using germ line cells results in permanent changes that are passed down to subsequent generations. If done early in embryologic development, such as during preimplantation diagnosis and in vitro fertilization, the gene transfer could also occur in all cells of the developing embryo. The appeal of germ line gene therapy is its potential for offering a permanent therapeutic effect for all who inherit the target gene. Successful germ line therapies introduce the possibility of eliminating some diseases from a particular family, and ultimately from the population, forever. However, this also raises controversy. Some people view this type of therapy as unnatural, and liken it to "playing God." Others have concerns about the technical aspects. They worry that the genetic change propagated by germ line gene therapy may actually be deleterious and harmful, with the potential for unforeseen negative effects on future generations. Somatic cells … Continue reading →

If you know me youll know Im a keen surfer and have spent years in Indonesia (now in Japan). This TEDx Talk by Dr. Dave Jenkins is inspirational and informative, as he describes their work at SurfAid International (2007 NGO of the Year). He describes how we can harness doing what we love for the good of others, but also discusses the importance of community connection and authenticity in service projects and the danger of the founder sydrome. Watch it maybe use it for inspiration for your CAS projects and share with those responsible for service in your school. Although they dont have aJustGiving page to add to my Biology4Good fundraising team, you can support them with donations (and T-shirts) here. .o0O0o..

Human genetics – Wikipedia

Posted: Published on November 30th, 2016

Human Genetics is the study of inheritance as it occurs in human beings. Human genetics encompasses a variety of overlapping fields including: classical genetics, cytogenetics, molecular genetics, biochemical genetics, genomics, population genetics, developmental genetics, clinical genetics, and genetic counseling. Genes can be the common factor of the qualities of most human-inherited traits. Study of human genetics can be useful as it can answer questions about human nature, understand the diseases and development of effective disease treatment, and understand genetics of human life. This article describes only basic features of human genetics; for the genetics of disorders please see: Medical genetics. Inheritance of traits for humans are based upon Gregor Mendel's model of inheritance. Mendel deduced that inheritance depends upon discrete units of inheritance, called factors or genes.[1] Autosomal traits are associated with a single gene on an autosome (non-sex chromosome)they are called "dominant" because a single copyinherited from either parentis enough to cause this trait to appear. This often means that one of the parents must also have the same trait, unless it has arisen due to an unlikely new mutation. Examples of autosomal dominant traits and disorders are Huntington's disease and achondroplasia. Autosomal recessive traits is one pattern of … Continue reading →

Posted: Published on November 30th, 2016

The MSPCAbelieves scientists ability to clone animals, to alter the genetic makeup of an animal, and to transfer pieces of genetic material from one species to another raises serious concerns for animals and humans alike. This pagewill explore issues related to genetic engineering, transgenic animals, and cloned animals. It will examine the implications of genetic engineering on human and animal welfare and will touch on some related moral and ethical concerns that our society has so far failed to completely address. Definitions Problems related to the physical and psychological well-being of cloned and transgenic animals, significant ethical concerns about the direct manipulation of genetic material, and questions about the value of life itself must all be carefully weighed against the potential benefits of genetic engineering for disease research, agricultural purposes, vaccine development, pharmaceutical products, and organ transplants. Genetic engineering is, as yet, an imperfect science that yields imperfect results. Changes in animal growth and development brought about by genetic engineering and cloning are less predictable, more rapid, and often more debilitating than changes brought about through the traditional process of selective breeding. This is especially apparent with cloning. Success rates are incredibly low; on average, less than 5% of cloned … Continue reading →
