Cloning Dialoge :: Argumentative Persuasive Topics

Cloning Dialoge The setting is a small colleges biology class where only three students turn up of twenty students have stick to class because it is the last day before spring break begins. The three students names are Andy, Kristen, and Eric. Seeing only three students in the class, the professor changes his lash material into a class discussion involving the recent scientific breakthrough in the field of cloning. During the discussion, the professor explains how the cloning of a sheep named Dolly was done. In addition, the students and the professor share their views on the advantageous and the detrimental side of cloning either humans or animals. Professor Good morning class I am sure that you all have heard about the recent scientific discovery in the process of cloning. If not, allow me to fill you in on this menstruation controversial scientific discovery. Last week, a Scottish scientist named Dr. Ian Wilmut from the Roslin Institute in Edinburgh, Scotland, successfully cloned an adult sheep. I said adult sheep because scientists already have the efficacy to clone sheep and calves, for farming purposes, from undifferentiated embryonic carrels. Is there any questions so far? Kristen Um, yes, professor. Would you please elaborate on the term undifferentiated cell? Also, the articulate cloning sounds like something you would hear from science fiction movies or novels--isnt the cloning process very complicated? Professor To answer your first question, Kristen, an undifferentiated cell is a cell that has the ability to create other specific cells, such as skin, hair, brain, and muscles, as it activates certain genes on chromosomes. For your instant question, the concept of cloning is real not that complicated to understand. Allow me to explain as I split Dr. Wilmuts cloning process into three steps. During the first step, udder cells from a six-year-old Finn Dorset ewe were taken and place into a culture dish. The culture dish, containing low l evels of nutrients, starved the cells, causing them to stop their dividing and hibernate its active genes. Meanwhile, the nucleus with its DNA from an unfertilized egg--also called an oocyte--taken from a Scottish Blackface ewe, is sucked out with a hair thin pipette, leaving the empty egg with all its cellular tools needed to produce an embryo. By the way, this process is called the nuclear transfer. Okay, now onto the second step the egg cell and a donor cell are placed next to each other and fused together, like soap bubbles, by an electric pulse.
