|
|
So the nuclear envelope can reform prior to cell division.
|
|
|
So there is sufficient energy available for the cell to divide quickly.
|
|
|
Because correcting mutations in the DNA would require a lot of energy in the new daughter cells.
|
|
|
So genetic information is correctly passed on to govern the cellular processes in the new daughter cells.

Detailed explanation-1: -Cells must replicate their DNA before they can divide. This ensures that each daughter cell gets a copy of the genome, and therefore, successful inheritance of genetic traits. DNA replication is an essential process and the basic mechanism is conserved in all organisms.
Detailed explanation-2: -DNA replication results in the duplication of DNA content in the cell, which is essential to maintain genetic continuity in the newly formed cell during cell division. Each cell receives the exact copy of DNA as a parent cell. This is required for growth and maintenance.
Detailed explanation-3: -It is important that the DNA is replicated before division because each of the daughter cells that are produced need to function independently once they are split. Further, DNA can only be produced with a template, so the replication must occur before division.
Detailed explanation-4: -Why does DNA need to replicate before cells divide? DNA replicates before a cell divides to give a complete set of genetic instructions to each daughter cell.
Detailed explanation-5: -Why would it be important to replicate DNA before a cell divides in mitosis or meiosis? In order for genetic information to be transferred into daughter cells.
