Dna Database - 1717 Words

For over a decade, there has been a controversial issue dealing with building a national DNA database. This issue has been brought up over the discussion of the actual database and what kinds of effects will come out of it, if it actually happens to go through. Some people think the database will be a force in crime fighting. Others think it is a violation of civil liberties. In the early 1900s, â€Å"fingerprinting,† a new crime-fighting database, was developed. With the exception of identical twins, no two people have the same fingerprints. Every person who was arrested was fingerprinted, and those fingerprints were inserted into the FBI computer database.

Bush did in fact sign into Congress the bills of the Newborn Screening Saves Lives Act of 2007 and the Genetic Information Nondiscrimination Act of 2008 (Alston). Congre ssman Ron Paul (R) stated that the Newborn Screening bill is the first step towards the establishment of a national DNA database, and is justified as a â€Å"national contingency plan.† However, surprisingly, he strongly opposed the bill in the first place. He insisted it threatened the liberties of Americans and told Congress â€Å"the federal government lacks both the constitutional authority and the competence to develop a newborn screening program adequate for a nation as large and diverse as the United States† (Floyd). Those of us in the medical profession should be particularly concerned about policies allowing government officials and state-favored interests to access our medical records without our consent †¦ My review of S. 1858 indicates the drafters of the legislation made no effort to ensure these newborn screening programs do not violate the privacy rights of parents and children, in fact, by directing federal bureaucrats to create a contingency pla n for newborn screening in the event of a public health disaster, this bill may lead to further erosions of medical privacy† (Floyd).

Once DNA is sent out to be tested, there are three different results: inclusions, exclusions, and inconclusive. An Inclusion result is when the DNA taken at the crime scene comes back and matches the DNA of the suspect, pointing that the suspect was at the scene of the crime.

Compare the structure and function of the xylem and phloem

Plants have two separate transport systems. A network of xylem vessels transports water and mineral ions from the roots to all other parts of the plant. Phloem tubes transport food made in the leaves to all other parts of the plant. Neither of these systems has a pump, this is because they are not as active as animals and do not need such rapid supplies of food. Neither xylem nor phloem transports oxygen as oxygen gets to a plants cell by diffusion. Both stems and roots contain xylem vessels and phloem tubes. In a stem these are grouped into vascular bundles arranged in a ring. In a root these are arranged in the centre forming a structure called the stele. Xylem tissue has the dual functions of support and transport. It contains several†¦show more content†¦As water evaporates from the cell walls of mesophyll cells, more water is drawn into them to replace it. The source of this water is the xylem vessels in the leaf. Water constantly moves out of these vessels, down a water potential gradient either into the mesophyll cells or along their cell walls. The removal of water from the top of xylem reduces the hydrostatic pressure. The hydrostatic pressure at the top of the xylem vessel becomes lower than the pressure at the bottom. This pressure difference causes water to move up the xylem vessels, causing a pressure difference between the top and bottom. The water in the xylem vessels is under tension; its walls may collapse inwards as a result of the pressure differences. Xylem vessels have strong lignified walls to stop them from collapsing in this way. The movement of water up through xylem vessels is by mass flow. This means that all the water molecules move together, as a body of liquid. In contrast to the structure of the xylem vessels, the sieve tubes in the phloem have end walls which when next to each other a sieve plate is formed. This is made up of the walls of both elements, perforated by large pores. Companion cells are closely associated with their neighbouring sieve elements. Numerous plasmodesmata pass through their cell walls, making direct contact between the cytoplasms of the companion cell and sieve element. The liquid inside the phloem sieve tubes is called phloem sap containing sucrose,Show MoreRelatedCompare and Contrast Xylem Tissue and Phloem Tissue, Including Their Respective Structures and Functions.888 Words   |  4 PagesCompare and contrast xylem tissue and phloem tissue, including their respective structures and functions.

Movie Review Cold Mountain Essay - 1149 Words

Film Review: Cold Mountain 1.) In the first assault scene at the beginning of the film, I thought that the north and the south both had strong motives and they were both willing to give it their all in order to preserve and defend their cause. This beginning scene if very heart broken because a lot of men died suddenly from one moment to the next. This makes me reflect on how hard and very divesting the civil war was not just for the women but also for the men who lost their families, wives, homes, and even their lives for the greater cause to which they were fighting for. The Union assault scene is very overwhelming to watch because during the civil war the tactics used were very harsh. For instance, when the Union placed explosive beneath the southern soldiers and blew them to pieces; not only destroying the men but everything in its path. At the beginning of the film one thing that can be noticed is that the north had a very different way of fight compared to the south. For instance, the south used trenches as way of defense and the north many of the soldiers were lined up in perfect lines which makes it seem as if the north was more organized then the south, in the sense of the way they defended their cause. 2.) I don’t think Inman was a traitor because he had dedicated so much time for the southern cause but after many attacks and attempts to fight back and after seeing so many men die, any man would have wished to escape from the horror of war and wanted to go backShow MoreRelatedMovie Review : Frozen Is The Hottest New Princess Movie Of 2013935 Words   |  4 PagesMovie Review: Frozen Frozen is the hottest new princess movie of 2013.

Analysis of Human Migration free essay sample

An Analysis of Human Migration Ever since humans learnt to grow crops as a steady source of food humans have migrated In search of conditions better suited to their needs and comforts. Although all of us but the 30-40 million that choose to live the nomadic life have abandoned that lifestyle and moved on to a more civilized modern era, migration still remains an option for those of us seeking to take residence In an alternate region of mother earth. The National Geographic Society [1] defines human migration as The movement of people from one place in the world to another for the purpose of taking up ermanent or semipermanent residence, usually across a political boundary. Migration Inside a landmass or political region Is called Internet migration and outside a physical or political border Is called external migration. For example Inside moving inside the continent of Australia would be internal migration but moving into a different continent overseas would be external migration. We will write a custom essay sample on Analysis of Human Migration or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page There are a variety of causes for migration, but they havent changed much through the years and remain fairly similar to the reasons our ancestors chose to migrate. These reasons can be categorized into two sections; these being push factors and pull factors. Push factors are reasons for leaving a region because of negative properties of the location and Pull factors are reasons for moving into a place because of positive properties of a location. Such factors can further be divided Into Environmental factors like climate, Political Factors Ilke war, Economic factors Ilke work, cultural factors Ilke education and utility factors like geographic location and socioeconomic status. Statistically speaking, the humans are extremely successful as a species. The 7 billionth human was born not long ago and the 10 billionth Is not far away, calculated to be born around the end of the century. The human race Is not only vast, we are also incredibly diverse and this is what defines us as a species. Meaning when we lost a part of our culture we lose a bit of what it means to be human. This brings us to one of the biggest drawbacks of migration, known as Cultural Extinction. Cultural extinction occurs when a family that Is part of a smaller culture migrates and the next generation of the respective family is only exposed to the native language and culture, since culture and tradition is only carried through families, the prospective bearer of this culture is burned out, ending a vein of this precious cultural blood. But our cultural diversity Itself poses a question. How Is It that we as a human race are so diverse in culture, and yet so similar? A research project named The Genographic project Was created by Spencer Wells for the purpose of answering this question and tracing human movement in prehistoric times. Even though the fields of palaeoanthropology and archaeology already enable us to access this Information, the Genographic project uses a newer method that allows us to find out how closely we are related to each other, enabling us to map out a family tree going back millions IOF4
