In mitosis, the important thing to remember is that the daughter cells each have the same chromosomes and DNA as the parent cell. The daughter cells from mitosis are called diploid cells. Diploid cells have two complete sets of chromosomes. Since the daughter cells have exact copies of their parent cell's DNA, no genetic diversity is created through mitosis in normal healthy cells.
In Conclusion. The core difference between narrative and expository essays is their style. While narrative paper allows the author to be creative and tell a story in a way he or she likes, expository essays follow some strict rules that one must abide.
Expository writers organize their ideas into paragraphs. When you are reading expository writing, you can tell where a new paragraph begins because the first line will be indented or the author will skip a line. When you compose expository writing, you should also organize your ideas into paragraphs.
