Human anatomy assignment question

“Briefly describe how a cell passes DNA sequence onto other cells, when it divides.” I have asked my tutor and she gave me a more detailed explanation of this question – Describe how you can have a section of DNA in a cell and when that cell divides into 2, both cells end up with apparently the same section of DNA. How does it get 2 copies? How do the 2 copies end up in 2 cells and not 2 copies in one cell and none in the other? 

Need about 150-200 words on this question, your help will be MUCH appreciated, as I have no clue how to answer this question. P.S. Need it 100% plagiarism free as it is for my UNI assignment. Cheers
