The a cell divides, it is important that each daughter cell receives an identical copy of the DNA. This is accomplished by the process of DNA replication. The replication of DNA occurs during the synthesis phase, or S phase, of the cell cycle, before the cell enters mitosis or meiosis.
The double-stranded parent DNA molecule gets separated and provides two template DNA strands for daughter strands synthesis. Enzyme DNA polymerase adds nucleotides complementary to template strands and synthesize daughter strands.
Answer:Movement makes dolphins stress which can make your insusceptible framework more vulnerable and the flare-up will spread to different dolphins and conceivably other species.
