The thrifty gene hypothesis postulates that, due to dietary scarcity during human evolution, people are prone to obesity. Their ability to take advantage of rare periods of abundance by storing energy as fat would be advantageous during times of varying food availability, and individuals with greater adipose reserves would be more likely to survive famine. This tendency to store fat, however, would be maladaptive in societies with stable food supplies. This theory has received various criticisms…

The debate on the extent of the effects of nature versus nurture has existed for centuries. Nature describes human genetics and heritable traits, and nurture expresses how humans are raised and their surrounding environment. Many psychology scholars disagree over the comparative contributions of genetics and experience. Plato alleged that both personality and intelligence level were hereditary, while Aristotle asserted that human’s knowledge and traits came completely from experience (Myers…

Scientific experiments and observations have led to many discoveries, which in turn have allowed scientists to develop a better understanding on the way diseases originate in humans. Molecular biology in particular has allowed scientists to discover the way in which domains, found in proteins impact a genome. Domains are autonomous folding units that carry out specific functions and mechanisms in a certain protein. These functions consist of being responsible for interactions in the cell, which…

still new there has not yet been a full treatment created. However, speech and physical therapy, along with the use of medication some of the symptoms may die-down and become less harsh. Like many other illnesses, this syndrome requires a medical diagnosis, specially prescribed for the child by a doctor (Rett Syn.). Although the medications can help the side effects die-down the cannot eliminate them completely. They can last for many years, or in many cases a lifetime. This means the child will…

Background: During vertebrate development, neurons differentiate before glial cells. Common progenitor model and heterogeneous progenitor model were proposed to explain this differential paradox. This paper aims to resolve the uncertain lineage relationship between the two differentiated cells and identify the basis for the fate of speciation. Hypothesis 1: pMN progenitor fate is biased by the position of the cell within the pMN domain. Experimental Approach: Transgenic…

and consequences that are associated with the inclusion of the whole genome sequencing into the newborn screening program. The WGS has been relatively successful in providing researchers with a more accurate conclusion of potential metabolic and genetic disorders of the newborns screened (Blackmann, 2015). This information as you have mentioned can be vital in creating early treatment plans for parents to consider for their child. However, due the WGS being a relatively new phenomenon it still…

During the past years biotechnology have been vastly developed and gene patent plays a big role in the society. So what is gene patent? Gene patent is the exclusive right to a specific sequence of DNA given by the government to an individual or organization that claims to have first identified the gene. Once granted a gene patent, the holder of the patent dictates how the gene can be used for 20 years from the date of the patent. Right now, gene patent is used in many companies for research…

There are many controversial issues throughout time that have risen and led countries to disagree to with one another worldwide. Eugenics and genetic engineering on humans is a topic that many believe crosses a major ethical boundary. Many scientists and ethicists believe that gene editing on human genes is unethical at certain degrees and it should not be done until the proper precautions have been overlooked and restrictions are made. Eugenics is the study of improving the qualities of the…

Accidently posted and was not ready so here is the rest of my disscussion; Sperm Donor Legal Issues Highlighted By Kanas Case This cases is about a Kansas Sperm donor being sued by the state for child support put himself in a percarious position by getting involved in a lesbian couple's do it yourself artifical insemination. Kansas law states that a sperm donor is not the fatherof a child if a doctor handles the artifical insemination. But…

We are began as a single cell, but by the time that we are an adult, we have trillion of cells in our body. This happen because our cells are constantly dividing and when they divide they make new cells. A group of cells form a tissue, a tissue form the organ, an organ compound the system of organ and then the individual. We all have this question, why our cells are dividing constantly? Cells divide to replace old or damaged cells, and also living organism can grow and reproduce. There are two…
