What is genetic engineering? Genetic engineering involves manipulation of cellular material to create changes in the structure of living organisms. Altering the DNA of a cell changes the attributes of cells created by later reproduction, ideally in a useful and beneficial way. The process is used to create plant or animal hybrids, to correct genetic flaws in an animal or human, or to utilize biological organisms to produce valuable chemicals (such as insulin). What are the concerns? While

101 Dr. Ferdinand The cell is the basic unit of life for all living things, while the DNA is the design for all passed down characteristics in living things. Both the cell and DNA have been studied and linked to the evolution process. From the beginning of the eukaryote cell unto the prokaryote cell there has been changes and the same goes for DNA. Changes in DNA sequences has contributed to different yet similar species over great periods of time. The cell which first existed in its prokaryote

parents and so forth over time. Genetics are the building blocks of physical traits. They are an important foundation to who a person becomes; how they will develop into adulthood. When reproduction begins, the tiny cell that results from fertilization of the egg at conception multiplies into trillions of cells that form the fetus. The sperm and ovum both contribute chromosomes that form the

today. It can be defined as the act of creating a new individual (reproductive) or organism (therapeutic) from the single cell of a parent subject. In reproductive cloning (human cloning) a parent subject is expected to act as a surrogate mother. Making the clone involves using the parent’s empty egg (nucleus and genetic code removed) combined with the nucleus of their own skin cells to create 1 embryo which is now a copy of them. Each time a procedure is formed a life hangs in the balance. This life

Importance of Speech Popol Vuh, written anonymously by Mayans and later translated by Father Ximenez, is a myth on the creation of humans through a process of trial and error. By examining the role of speaking and its relationship to humans in Popul Vuh, we can see that the ability to speak and reason defines humanity. Speech is first introduced as just existing when the world had just begun. Any form of life had not existed except for the sea. Then the myth illustrates the power of speech when

once cellular life begins, or when the cells that constitute you begin to grow and divide. The problem with this view is that biology has proven to us that cellular life does not simply “begin”, it is a complex, continuous cycle. Science has shown that every cell that is alive in your body is the result of a split of some prior cell, so technically your body and its constituent cells have been “alive” for about 4 billion years. More specifically, the cells that constitute the potential DNA that could

and feelings naturally needed for survival. When the hypothalamus is informed of a condition, it secretes chemicals and hormones to the blood stream to signal the body for an innate and necessary response. Hunger, thirst, self-defense, and sexual reproduction are included in that list of important sensations. Just like the brain tells an organism when it is hungry, it also signals the body to react when an attractive being walks by. "The heart pounds, the muscles tense; he or she feels dizzy and
