Detailed explanation-1: -DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
Detailed explanation-2: -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-3: -DNA must replicate (copy) itself so that each resulting cell after mitosis and cell division has the same DNA as the parent cell. All these cells, the parent cell and the two new daughter cells, are genetically identical.
Detailed explanation-4: -Due to the process of DNA replication, each daughter cell gets an equal amount of DNA. The process of DNA replication helps in the inheritance process by transfer of the genetic material from one generation to another. Therefore it is required for the growth, repair, and regeneration of tissues in living organisms.
Detailed explanation-5: -Before a cell divides, it must first copy (or replicate) its entire genome so that each resulting daughter cell ends up with its own complete genome.
