Detailed explanation-1: -When one cell divides into two, both must have a copy of the genetic information. Therefore, before cell division occurs, the genes must also make duplicates of themselves so that all of the important genetic information ends up in each of the new cells.
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: -Each time a cell divides, it must first duplicate its genetic material in a process called DNA replication. Because defects in this process can cause mutations that eventually lead to cancer, understanding the details of how replication works could point to possible cancer treatments.
Detailed explanation-4: -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.
