Summary Introduction
Introduction:
In cell cycle process, cell starts to divide and replicate itself. Two phases of cell cycle are: interphase, which includes replication of DNA, and M phase that includes mitosis. Replication of DNA occurs in interphase prior to mitotic phase of the cell cycle.

DNA or deoxyribonucleic acid is the hereditary material in humans and almost all other organisms. Nearly every cell in a person's body has the same DNA. This, in turn, replicates in the non-dividing phase of the cell cycle which is
a. telophase
b. cytokinesis
c. metaphase
d. interphase
Which of the following statements is true?
a. once a person reaches maturity, cell division stops unless it is to repair a wound
b. cell division in an adult signifies cancer
c. some specific cells throughout the body retain the ability to divide and replace themselves
d. growth continues on throughout life of an adult human
During this stage of mitosis, the chromatin coils to form chromosomes, the nuclear envelope disappears, the nucleolus dissolves, spindle fibers are formed, and the centrioles migrate to the poles. a. prophase b. metaphase c. anaphase d. telophase
