If the amount of DNA in two new cells is half of the original amount which phase of the cell cycle is malfunctioning

Answer 1

If the amount of DNA in two new cells is half of the original amount, it suggests that the cells underwent a process where the DNA was not properly replicated before cell division. This scenario indicates a malfunction during the S phase (synthesis phase) of the cell cycle, where DNA replication occurs. In a normal cell cycle, the DNA must be duplicated during the S phase so that each daughter cell receives a full set of chromosomes during cytokinesis. If the DNA is not replicated, the resulting daughter cells will end up with only half the genetic material of the original cell.
