Detailed explanation-1: -Which statement BEST describes the primary function of DNA replication? To ensure daughter cells have a complete copy of DNA.
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: -What does DNA do? DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
Detailed explanation-4: -DNA (Deoxyribonucleic acid) replication occurs in the synthesis (S) phase of the cell cycle. Thus, the DNA doubles before the cell enter mitosis, where the cell divides to form two daughter cells.
