DNA electropherises

- -

DNA electrophoreses is a process in which a DNA maroon is cut by a restriction enzyme at a certain point so it can be mensurable and compared with other DNA. The purpose of the lab was to determine the military chaplain of a child by comparing the childs DNA with that of the mother and two possible fathers. The childs DNA fits a combination of the real father and mother.

        Electrophoresis begins with the pouring of the gel. The gel is an auger poured into a wet bath. Combs are then placed in the forming gel to build wells where the samples are then placed. The gel is placed in the electrophoresis apparatus and fill up with the samples. The different samples are firm into the wells formed in the gel. The DNA samples are loaded using a measuring instrument called a micropipeter. there is then an electric current passed through the gel to tell apart the DNA fragments. The current separates the DNA segments by moving the little ones farther than the large ones. Every DNA sample separates differently. This elbow room they can be compared with others. It is highly unlikely that two samples get out have the same results.

        

        

        

                                            Leukemia

        Leukemia strikes all ages and both sexes. In 1995 approximately 20,400 people died from Leukemia.



The all time five year selection rate is 38%. This rate has gone to 52% in the mid 1980s. Approximately 25,700 cases were reported in 1995 alone(American Cancer Society-leukemia, 1995).

        Leukemia is a form of cancer in the blood cells. Most forms of Leukemia go across in the white blood cells. These abnormal cells reproduce in large quantities and look and perform differently than normal cells(MedicineNet-leukemia, 1997).

Right instanter the causes of Leukemia are unknown. Some studies have shown...
