Cancer is not one single disease but a complex of many diseases. About two hundred distinct types of cancer have been recognized. These can be grouped into four main types: carcinomas, sarcomas, lymphomas and leukemias. True and leading cause of cancer. Where does it stem from. It is agreed by most that, “The immediate cause of cancer must be some combination of insults and accidents that induces normal cells in a healthy human body to turn malignant, growing like weeds and sprouting in unnatural places”. It is also agreed in the scientific community that cancer is “a disease of DNA”, however this does not really get to the root of the problem.
Recombinant DNA and the Human Gene : Restriction enzymes or restriction endonucleases, and more than 100 of these enzymes have been isolated. After the human gene (gene of interest) that codes for the desire trait is located on the chromosome restriction enzyme does it job, by cutting out the gene from the DNA. Now, the two ends of the human gene will be those that will link up with the open ends of the plasmid. Cell division is a normal process in multi-cellular organisms. Growth and repair (replacement of dead cells) take place as a result of cell division (mitosis). Except for cells like the liver and brain cells, which rarely divide in the mature adult, most cells undergo frequent division. Sometimes, however, cell division becomes very rapid and uncontrolled, leading lo cancer. It should be clearly understood that rapid growth means a high rate of cell division for a particular cell type. It is possible for perfectly normal cells, e. g. the blood-forming cells, to have a higher rate of division than some cancerous cells.
The human manipulation of DNA “Will the human manipulation of DNA provide significant benefits to today’s society?” Human manipulation of DNA, also known as genetic engineering and recombinant DNA technology, is a process that involves combining DNA, and inserting the newly recombined DNA into cells to be expressed through protein synthesis. The human manipulation of DNA can be beneficial and disadvantageous. It allows genetically engineered (GE) proteins to be manufactured, aiding those with cardiac issues, and can increase genetic diversity.
