Purpose: Restriction enzymes cut DNA at a certain palindromic sequence. Three samples of lamda DNA set up to be cut with restriction enzymes PstI‚ EcoRI‚ or HindDIII. There were also two more samples‚ one of these samples was not mixed with any restriction enzyme and the other was a marker‚ which used an enzyme which creates fragments with a known number of base pairs used to create a standard curve. All five samples were put through agarose gel electrophoresis in order to estimate the amount of

This experiment is to determine the unknown DNA plasmid using restriction enzymes and conducting electrophoresis finally comparing the resulting fragments with the known restriction map. In this lab‚ it succeeds in showing the fragments. In this report we will discuss the‚ results‚ limitations and possible errors. Introduction In biology restriction enzymes are used in several ways to modify and manipulate DNA molecules. One common use is to compare pieces of DNA from one that is unknown‚ with fragments

Interior of Artist’s Studio: Hugh Ramsay (1901) The still life genre; or the depiction of the inanimate‚ allows for the manipulation of subject matter. An object can be changed‚ moved around or kept in place for hours on end. This unrestricted control of the subject can be used to create uniquely thought out and deliberate works. Conversely‚ objects can be depicted as they are‚ with no sense of manipulation. Things fallen on the floor or a bag left on a chair can illustrate something unrefined‚ untouched

Restriction enzymes (or restriction endonucleases)‚ originally isolated from Haemophilus influenzae in 1970‚ are enzymes within a cell that cleave foreign DNA within a specific and predictable nucleotide sequence (known as a restriction site) regardless of the source of such DNA. Such restriction sites

Immigration to the United States is a complex demographic phenomenon that has been a major source of population growth and cultural change throughout much of the history of the United States. The economic‚ social‚ and political aspects of immigration have caused controversy regarding ethnicity‚ economic benefits‚ jobs for non-immigrants‚ settlement patterns‚ impact on upward social mobility‚ crime‚ and voting behavior. American immigration history can be viewed in four epochs: the colonial period

The Immigration Reform and Control Act of 1986 (IRCA) conducted by President Ronald Reagan is viewed as one of the most important policy implementations in U.S. immigration history. As drafted‚ IRCA was incorporated to be a policy to control and prevent all illegal immigration that took place in the U.S.‚ but the policy was for basically directed at stopping the flow of Mexican immigrants that continues to this day‚ to be the largest immigration flow in the world.

At the beginning of the 19th century the dominant industry of Ireland was agriculture. Large areas of this land was under the control of landowners living in England. Much of this land was rented to small farmers who‚ because of a lack of capital‚ farmed with antiquated implements and used backward methods. The average wage for farm labourers in Ireland was eight pence a day. This was only a fifth of what could be obtained in the United States and those without land began to seriously consider emigrating
