Can there be mitosis without dna replication
Webanswer choices. Crossing-over occurs prior to cell division. Mutations are corrected before the cell divides. Genetic variation is created in daughter cells. Each daughter cell gets an exact copy of the cell’s DNA. Question 2. 120 seconds. Q. The following diagrams are of a cell in the different phases of the cell cycle. WebMitotic cell division cannot take place without DNA replication in S phase. Two important events take place during S phase – one is the synthesis or duplication of DNA and the other is the duplication of the centriole. DNA duplication is important as it maintains the chromosome number in the daughter cells and hence Mitosis is an equational division.
