Gene duplication

Personal Identity is a very debatable subject. How do you know you are you, even growing up are you still the same person you were at age 5. I believe in the psychological continuity theory the survival of the psychology makes the person them. There is the opposing argument called the duplication argument, this argument says it “Relies on the transitivity of identity: If A is numerically identical to B and B is numerically identical to C, then A is numerically identical to C.” But your psychology is impossible to be duplicated there can only be one you at one place at a time no one can have your exact memories. To me I believe the argument against the psychological continuity theory fails. This debate is important to me because the thought…

claims that “it seems clear as anything in philosophy that from A is B and C is B where by ‘is’ we mean identity, we can infer, A is C” (A Dialogue on Personal Identity and Immortality, page 32). Thus, if we were to duplicate Person B twice, resulting in Persons A and C, both Persons A and C would be Person B. Thus, both Persons A and C would have the same memories as Person B, which would mean they both have the same identity. However, personal identity is supposed to be unique. That is, only…

Genome duplication caters sources of genetic material for mutation and selection to act upon- making new evolutionary opportunities possible. In the last century, genome duplication has been viewed as a dominant factor in the evolution of eukaryotes. As an outcome, most people have disputed that genome duplication is a leading factor in the evolution of complexity and diversity (Crow 2005). Although many people believe this, no correlation has been made clear confirming whether this is true.…

Genome Evolution Did you know that the Tasmanian Devil’s genome is rapidly evolving to resist a deadly disease that has killed eighty percent of their population since 1996? To most people that means little to nothing, because most people don’t know what a genome is let alone the process in which it takes to evolve or for Scientists to discover the evolution. In the following paragraphs we will discuss what genome evolution is, how genomes are able to be compared and how the size can…

ID #: 1259993 BIOL 3311 Fall 2014 Date: October 2, 2014 Gene: Bar TA Instructor Name: Fahmi Mesmar Lab Section: 16258 Writing Assignment 3: Eye morphology of Drosophila melanogaster; Bar mutation effects on ommatidial development of the compound eye. Introduction: Drosophila melanogaster have been used for centuries as model organisms due to their relatively small size as well as their inexpensive and simple diet. Fruit flies also have to ability to reproduce in large amounts considering…

cyanobacteria and higher plants (Shively et al., 1973). The multiple nuclear gene encoding small subunits of Rubisco is called rbcS. rbcS exists only in Rubisco form 1 so that it is not absolutely essential for carboxylate activity, however it is apparent that rbcS influence catalyze indirectly as following possibilities (Spreitzer et al., 2002). rbcS could have a role to determine the carboxylation efficiency…

their Knees, by Emily DeMarco. For example, the article describes how the Dachshund gene was duplicated and activated in the patella region which formed kneecaps, providing flexibility (DeMarco, 2015). In class I learned about the different types of errors that can occur during DNA replication and repair. I learned that duplication can occur through replication slippage or unequal crossing over. Also, three arrangements of duplications can occur, which are known as tandem, reverse tandem, and…

Duchenne Muscular Dystrophy (DMD) is a rare single gene disorder affecting 1 in 3,500 boys. The muscles of the affected person weaken and waste away (atrophy), usually beginning in the lower limbs and then spreading to the upper body as the disease progresses (1). This disorder is caused by recessive mutations in a gene called dystrophin. The dystrophin gene is located on the X chromosome (Xp21.2). Because the X-linked disorder is recessive it occurs mostly in males because males who inherit the…

evolutionary relationship among organisms. We are able to identify genes that are conserved among the species. We can also identify genes that give organisms their unique and complex characteristics (Comparative Genomics Fact Sheet). This allows us to make inferences regarding the rate of evolution of particular genes, duplication…

3500 boys are born with DMD however very rarely affects girls with a 1 in 50million chance. It is caused by a small mutation in the DMD gene and it is inherited by families in an X-linked recessive fashion. Those who suffer from DMD generally lose muscle function which often occurs in weakness and mostly develops…
