Classical genetics

the Bayer CropScience (www.bayercropscience.us), you can find the type of corn you need and give you information on what that specific strain can protect or carry. Corn has been modified to contain vitamins that we need, to have pesticides in the genetic information, the size of corn, and the shape of corn. GMO has modified sweet corn that produces its own insecticide called Bt Toxin. Bt…

In the 1920s, the field of genetics saw many groundbreaking discoveries. The research of scientists such as Thomas Hunt Morgan and Hermann Joseph Muller proved the existence of chromosomes and genes as well as showed how mutations can be influenced and passed on to offspring. Geneticists from this decade used study results to form a more complete understanding of previously constructed theories. Genetic research in the 1920s significantly advanced scientific thinking and understanding…

Within modern Genetics An international scientific research project, Human Genome Project, was declared complete in 2003. It remains the world's largest collaborative biological project, identified and mapped all the genes in the human genome. In the past twenty years, research, techniques, and knowledge in genetics have widely expanded, benefiting from the Human Genome Project and other major advances in discovery research and diagnostic technologies (Hawkins). For example, genetic screening,…

DNA mutations are in other words DNA changes. Any changes in DNA can be from spontaneous mutation, in order to adapt to the continuous changing environment, or induced mutation, which it is caused from dangerous exposures such as to carcinogens or radiation. Moreover, three main steps a DNA chain goes through to build proteins are, DNA to mRNA (messenger deoxyribonucleic acid), and then the end result is protein. Furthermore, DNA changes, in which can occur in a single or multiple nucleotides on…

Congenital optic nerve hypoplasia (ONH) is a condition in which one or both optic nerves are not fully developed, giving the appearance of abnormally small, pale optic nerve heads upon fundus examination (AAPOS, n.d.). In comparison to the size of the disc, the retinal blood vessels appear larger than normal, when in actuality the vasculature is of normal caliber (Kaur et al, 2013). This non-progressive developmental abnormality is typically characterized by a combination of neurological,…

members. The results were ride ranging (with biological parents having a somewhat weak form correlation of .42 while identical twins in the same environment had a correlation of .86), but the conclusion remained the same: Genetics alone do not completely explain intelligence. If genetics don't explain intelligence alone, then it is important to look at what else could influence it to properly understand how we, as a society, can provide every citizen the most equitable education possible. Table…

of knowledge to breed seeds for their most desireable traits. Today, 90 percent of all corn, soybean, canola and sugar crops are altered either in the laboratory in ways that cannot be achieved with traditional farming techniques or inserted with genetic material, to exhibit traits that withstand drought and soil erosion . Many argue that GMO usage harms the environment and human health, while others believe that GMO usage provides pest and drought resistance for crops, and allows for third…

took a voyage on the HMS Beagle that opened Darwin’s eyes to the idea of evolution. He had one simple idea that all living things are related. Natural selection plays a big role in evolution. There are four parts to natural selection and they are genetic variation, overproduction of offspring, struggle for existence, differential survival and reproduction. My Biology class did another lab called “Origami Bird Lab.”. In this lab we started with three birds made out of paper and straws they all…

Case Background In Association for Molecular Pathology v. Myriad Genetics, Inc., the Court addressed the patentability of human genes. Myriad Genetics Inc. had identified precisely and then isolated two genes, BRCA1 and BRCA2 which can substantially increase the risks of breast and ovarian cancer. As a result, soon thereafter, the company began offering screening tests to members of the public able to afford them, and filed for patents related to the discovery and associated assets. Myriad…

RETINOBLASTOMA Retinoblastoma is “an embryonal tumor of developing photoreceptors” (Williams), and the majority of cases present in young children age five or younger. It is usually present at birth. Retinoblastoma can also be genetic in some cases. Only 150-350 cases present worldwide each year. It is one of the rarest forms of cancer. I chose to research this cancer because of its rarity. Originally, I wanted to research AML (acute myeloid leukemia), and quickly realized I craved to research…
