In the article from LA Times on March 1‚ 2013‚ “Sleep Deprivation has genetic consequences‚ study finds” Eryn Brown states that people who have lack of sleep have higher risk of disease. Brown says that people who lack more sleep than others shut down genes that heal the body and are more likely to be obese‚ suffer from “cardiovascular woes”‚ and can have several diseases. She supports her claim by using types of evidence by a study conceived by scientists‚ then the statistics of people that are

Down syndrome is a genetic disorder‚ often referred to as trisomy 21 because the cells for chromosome 21 are trisomic‚ meaning an individual with Down syndrome would have 47 chromosomes in all of their body cells. Down syndrome is a genetic disorder‚ there are 3 different types of chromosomal changes which can lead to Down syndrome: complete trisomy 21‚ whereby the nondisjunction occurs during the formation of the egg or sperm cells meaning all body cells will have 47 chromosomes. This is the most

obstacles are overcome. One main obstacle is the complexity of the relationship between DNA and human traits. Will we ever know which genes influence intelligence and master how to manipulate them? However‚ as computer technology and understanding of genetic increases‚ it may only be a matter of time before a number of human gene-trait relations are defined clearly. Another obstacle is the ethics of human experimentation. Failures in human experiments should not be accepted‚ so confirmation of the

polygenic inheritance and pleiotropy polygenic inheritance is a non-Mendelian form of inheritance in which a particular trait is produced by the interaction of many genes. Polygenic inheritance refers to the kind of inheritance in which the trait is produced from the cumulative effects of many genes in contrast to monogenic inheritancewherein the trait results from the expression of one gene (or one gene pair). In humans‚ height‚ weight‚ and skin color are examples of polygenic inheritance‚ which does

The statistics that we predicted were really close to what numbers we actually got. However‚ the PV92 did not fit the hypothesis. The reason that the PV92 traits differed drastically than what was expected was due to genetic drift. As genes were passed down from parent to child‚ the genes were in a battle as to who was going to be the champ. With generations passing‚ the heterozygotes were going downhill‚ while the homozygotes were taking the upper hand. While we might

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

Genetic engineering Explain how this technology works. Genetic engineering otherwise called genetic modification and can basically be described as the ‘direct manipulation of an organism’s genome’ which is the complete set of genetic material of an animal‚ plant or other living thing. This direct manipulation works by using modern DNA technology. This ‘involves the introduction of foreign DNA also known as synthetic genes into the organism of interest’ or curiousity. Genetic engineering does not

Genetic counseling is the process that evaluates family history‚ ordering genetic test and evaluating medical records. Genetic counseling is a service that helps the people to translate scientific information into practical information. Genetic tests determine if there are gene-carrying traits or inherited disorders. Genetic tests done by testing small amount of body tissue or blood sample. The gene is made up of DNA sequence molecule‚ which is building blocks‚ the hereditary grouped in specific
