Genetically Engineered DNA Mutations and segments
This planet sustains various life forms and over time these organisms have evolved to better survive in the environments in which they live. Humans are constantly trying to improve the world and the organisms in it. In order to achieve this goal, there is a powerful tool scientists are using called DNA Technology. It is this technology that allows humans to modify, create, and/or destroy life as we know it. In this paper I will review the cloning of cells and new DNA segments and will discuss what is best for improving our earth.

REVIEW
Cloning of cells

The definition of mutation is a sudden departure from the parent type in one or more heritable characteristics, cause by a change in a gene or a chromosome. Mutations can be inherited or acquired when cells divide incorrectly. Scientists aren’t able to stop mutations from occurring; But, they are able to genetically modify and clone cells to fix the mutated ones.
The article “Landscape of somatic single nucleotide and copy-number mutations in uterine serous carcinoma”, written by Richard P. Lifton, explains how mutations in “latter tumors showed hallmarks of defects in DNA mismatch repair. “ Genetically cloning cells to correct mutated cells so they help delete imperfections in segments of DNA. According to Lifton, somatic variation was found to have helped delete a small mutated segment of DNA.
In the article “Half or more of the somatic in cancers of self- renewing tissues originated prior to tumor initiation”, Bert K. Vogelstein creates a mathematical model for the evolution of somatic mutations. The model makes predicts somatic mutations in tumors depending on the age of the patient at diagnosis. Since large amounts of somatic mutations are found in most solid tumors, alterations are focused more on the tumor. According to Vogelstein the accumulation of mutations provides data that somatic mutations in an average adult...
