|
At what point in the cell cycle does DNA replication occur and why?
|
|
before a cell divides, to provide each of the two resulting cells with a complete set of DNA instructions
|
|
|
before a cell divides, to ensure that DNA will fit into the resulting cells
|
|
|
during cell division, to ensure that the DNA will fit into the resulting new cells
|
|
|
after a cell divides, to provide each of the resulting new cells with a complete set of DNA instructions

Explanation:
Detailed explanation-1: -During interphase, the chromosomes are decondensed and distributed throughout the nucleus, so the nucleus appears morphologically uniform. At the molecular level, however, interphase is the time during which both cell growth and DNA replication occur in an orderly manner in preparation for cell division.
Detailed explanation-2: -DNA replicates before actual cell division so that identical set of the genome of the parent cell is received by each daughter cell.
