Explanation:
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.
Detailed explanation-2: -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.
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.
