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

The scientific studies conducted for epigenetics have given light and has helped disprove a common fact that DNA is a person’s destiny. A person's 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 child's 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 victim's 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 drastically 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 a
