The Contributions Of DNA Sequences DNA Is Not Destiny

DNA is Not Destiny Deoxyribonucleic Acid (DNA) is made up of nucleotides which contain three parts: a phosphate group, a sugar group, and one of four types of nitrogen bases. DNA then forms a double helix, with alternating phosphate and sugar groups linked to a chain of nucleotides. DNA is important because it gives instructions to an organism on how to develop, survive, and reproduce through DNA sequences. These sequences contain instructions on how to make proteins, which are complex molecules that do most of the work in the human body. DNA Sequences that contain instructions on how to make proteins are genes which also determine physical traits. The complete DNA instruction book, or genome, for a human, contains about three billion†¦show more content†¦The scientific studies conducted for epigenetics have given light and has helped disprove a common fact that DNA is a person’s destiny. A persons destiny is instead due to multiple factors. These factors range from the mother’s diet during pregnancy to the person’s lifestyle (Watters 33). An experiment conducted by Randy Jirtle, a professor at Duke University, has proven the mother’s diet during pregnancy has a profound impact on childs epigenome. The experiment took mice that have the agouti gene and bred them. Typically, the child would have the agouti gene like the parents, which would make them yellow, fat, and prone to diseases, but it did not. The offspring did not phonetically posses the agouti gene but were slender brown mice. This was due to the mother’s rich diet of methyl foods rich during pregnancy which altered the epigenome and phonetically turned off the agouti gene (Watters 33). These methyl-rich foods are the type of victims usually found in the victims pills pregnant woman take so this data can be applied to humans like most mice experiments and results from them. Scientists have conducted other studies and have found that identical twins having the same DNA can be d rastically different by the time they are twenty years old due to their different experiences in life (Fraga, Mario F., et al). Epigenetics marks are affected by experiences aShow MoreRelated The Pros and Cons of Human Cloning Essay3781 Words   |  16 Pagesrequire 18 years to reach adulthood just like everyone else. Consequently, a clone-twin will be decades younger than the original person. There is no danger of people confusing a clone-twin with the original person. As with identical twins, the clone and DNA donor would have different fingerprints. A clone will not inherit any of the memories of the original person. Because of these differences, a clone is not a xerox copy or double of a person, just a much younger identical twin. Human clones would haveRead MoreGenetic and Environmental Factors of Intelligence Essay example3390 Words   |  14 Pagesthey age, diversity and availability of choices expands, and if these choices are at least partially determined by genetic facto rs, the influence of environment is thereby diminished. Benno (1990) suggests the difficulty in determining relative contributions lies in the interdependency of genes and environment. Lewontin, Rose, and Kamen (1984) suggest that heritability of IQ is irrelevant and unimportant, as heritability is not synonymous with unchangeability. They attribute this confusion to a generalRead MoreProject Mgmt296381 Words   |  1186 Pagesbaseline development 7.3.2.1 Earned value system (F.4) 7.3.2.4 E.V., performance status report 7.3.2.2 E.V., forecasts 7.3.2.3 EV., to complete index (EAC) 7.3.2.5 Schedule and cost variance Developing a Project Plan 4.2.2 Planning tools 6.2 Sequence activities [1.2] 6.5.1 Bar and milestone charts 6.5.2 Critical path method (.2) 6.5.2.6 Lead and lag activities [6.2.3] F.3 Project duration Chapter 14 Project closure Closure report 4.5.1.4 Organization processes (.5) [4.5.3 4.6.3.2]Read MoreDeveloping Management Skills404131 Words   |  1617 Pagesit slide and do nothing in order to avoid a confrontation. b.
