During which phase is the DNA duplicated?
Answer:
The DNA is duplicated during the S phase of the cell cycle. The cell cycle consists of several phases, including the G1 phase, S phase, G2 phase, and M phase. The S phase, also known as the synthesis phase, is the phase in which DNA replication takes place.
During DNA replication, the DNA molecule unwinds and separates into two strands. Each strand serves as a template for the synthesis of a new complementary strand, resulting in the formation of two identical DNA molecules. This process is essential for cell division and the transmission of genetic information to daughter cells.
The S phase is a critical stage in the cell cycle because it ensures that each daughter cell receives an exact copy of the genetic material. After DNA replication occurs during the S phase, the cell proceeds to the G2 phase, where it prepares for cell division during the subsequent M phase.
In summary, DNA duplication occurs specifically during the S phase of the cell cycle, ensuring the accurate transmission of genetic information to daughter cells.
