In biology, one only comes to know so much about a subject before one begins to compare it to other things. As humans, we are comparative by nature—always wondering what is the best between multiple things (if it even is) and why. That is why we do it, ultimately. We feel that we must answer the question “Why?” In this biographical paper, I will be analyzing two very different processes: DNA Replication and the Polymerase Chain Reaction (PCR). It is that each of these individual processes carries much importance. DNA replication is important in the life of a cell, more so the division, because when a cell divides both of the daughter cells need identical DNA to function properly. PCR is important in that it allows amplification of DNA and isolation of DNA. PCR is also used to analyze DNA samples (used widely in crime scene investigation units) and allows scientists to work with DNA samples they previously could not. I will give a brief overview as to what the purpose of each process is, but I will focus more so on the individual differences and on the individual similarities between the two processes.
DNA Replication is a very intricate, deliberate and interesting process that, essentially, makes us who we are and keeps us that way. This process is highly important because DNA carries all of the information for making every single protein within a cell and these proteins implement all of the functions within us. When one of our cells (somatic cells) reproduces it passes on all of this information to the daughter cells through mitosis. The actual DNA Replication, however, is not so simple. It requires a number of enzymes and follows a pattern unique to each individual strand of DNA being replicated.

...iming to occur. More differences include that DNA replication is semi discontinuous and both strands are manufactured quite differently—a leading strand is continuously made while a lagging strand is made in fragments (Okazaki fragments) while in PCR, the DNA strands are replicated equally. More differences encompass the end result of both processes. In DNA replication the end result is two complete strands of DNA, whereas in PCR the replicated DNA is only a fragment of the original strand. A huge difference between the two processes is how they deal with the “road blocks” of replication. When DNA replication fails to produce two strands of equal length, then it enlists the help of telomerase that extends the ends by using a complementary and repetitive sequence. In PCR, restriction endonuclease is used in order to isolate the targeted DNA sequence for replication.

Essay on Biology and Philosophy of Love - Biology and Philosophy of Love What does it mean to love another person. This question is one that virtually every person has asked himself at some point; virtually every school of thought that exists has attempted to provide an answer of some sort. In this paper I will explain my own attempt at answering that question, from the perspective of an amateur philosopher; then I shall delineate the answers that some biologists have given. We shall see that, while at first these two sets of answers might appear to be quite different, there are in fact some interesting and notable similarities....   [tags: Biology Essays Research Papers]

Gender Roles: Biology or Culture Essay - Brettell and Sargent open their book Gender in Cross Cultural Perspectives with a question: What is the role of biology in human behaviour (Brettell and Sargent, 2009, 1). Ward and Edelstein approach this question using cross-species analysis. They compare chimpanzee biology and behaviour to humans. There are four reasons that Ward uses comparisons to chimpanzees. First, because chimpanzees represent our closest genetic relative and second, the social activities and behaviours may be reflective of human ancestors....   [tags: Gender in Cross Cultural Perspectives]

Beauty, Biology, and Society Essay - Beauty, Biology, and Society What is beauty. How do human beings decide who is attractive and who is not. Society is full of messages telling us what is beautiful, but what are those definitions based on. Do we consciously decide whom we are attracted to, or is biology somehow involved. The issue of beauty and how we define it has been studied for centuries. Scholars from all fields of study have searched for the "formula" for beauty. Darwin in his book The Descent of Man wrote, "It is certainly not true that there is in the mind of man any universal standard of beauty with respect to the human body....   [tags: Biology Essays Research Papers]

Gender Role Behaviors: Biology and Society Share Responsibility Essay - There are many different facets to the nature versus nurture argument that has been going on for decades. One of these, the influence of nature and nurture on gender roles and behaviors, is argued well by both Deborah Blum and Aaron Devor, both of whom believe that society plays a large role in determining gender. I, however, have a tendency to agree with Blum that biology and society both share responsibility for these behaviors. The real question is not whether gender expression is a result of nature or nurture, but how much of a role each of these plays....   [tags: Gender Role Behaviors and Attitudes]

Essay about Biology, Pragmatism and Contradiction - Biology, Pragmatism and the Question of Contradiction ABSTRACT: In this article I present H. R. Maturana's work as an alternative that reinforces pragmatism in the task of thinking philosophy through the evolution of biological species. I try to demonstrate how Maturana's biology dilutes the principal argument against American Neo-pragmatism. This criticism uses the argument of performative contradiction as it has developed in the European Neo-Kantian philosophy. Thus, I begin by presenting Apel....   [tags: Philosophy Philosophical Papers]

Biology: Mutations and Transformation Essay - ... 4. If these mutations exist then there must be countless amounts of mutations that result in unviable zygotes. Part Five – Experimental Possibilities To find the different types of mutations a genome would need to be sequenced. Next the genome would need to be bombarded with things that could mutate the sequence. The sequence could then be sequenced to find out where the mutations occurrence. The genome would then need to be manipulated synthetically to find out what effect the mutations occurred....   [tags: living organisms, artificial mutations] 1326 words

Cellular Biology Essay - My research topic is the controversy behind stem cellular biology. This topic is a very modern topic and it has garnered quite the negative persona by the masses. This negative connotation behind stem cellular biology is the reason I chose this topic. Rather than just following the herd and claiming stem cell is a dangerous science I would rather attempt to fully understand the science and form my own beliefs on this controversial topic. The research process has proven to be quite the learning experience in choosing reliable sources....   [tags: biasses, science, embryotic]

Essay on Adolescence: Defined By Biology or Society? - Adolescence begins in biology and ends in society. The definitions we accept to describe the onset of adolescence revolve around puberty, biological changes of the body. Therefore I consider adolescence to begin in biology. Adolescence ends in society. Entrance into adulthood marks the end of adolescence. The definitions of who is considered an adult are defined by society and therefore I contest that adolescence ends in society. The onset of adolescence is marked by a sudden increase in the production of many hormones in the body....   [tags: Adolescent Behavior] 687 words

My Experience with Biology Essay - My Experience with Biology To all who know me, they know how I can’t stand anything that is gross and slimy, or possibly get me in any way, shape, or form dirty. (I can’t stand to be dirty at all!) When I go to the doctors, I can’t even stand to see the nurses poke my arm with a long, cold, sharp needle, so they can get a blood sample. I can’t even stand to watch the shows on the Discovery channel where they are operating on any part of the human body and there is blood oozing from the open flesh of a human being....   [tags: Personal Narrative Writing] 1655 words
