Answer:
1. well they should include Definition of DNA synthesis: DNA synthesis, also known as DNA replication, is the process by which a cell makes an exact copy of its DNA. It is essential for cell division and the transmission of genetic information to daughter cells.
2. S phase.
Step-by-step explanation:
The cell cycle is the series of events that take place in a cell leading to its division and duplication. It consists of several phases, including the G1 phase (Gap 1), S phase (Synthesis), G2 phase (Gap 2), and M phase (Mitosis).
During the S phase, DNA synthesis or replication takes place. This is the stage where the cell's DNA is replicated to ensure that each daughter cell receives a complete set of genetic information. DNA replication is a complex process that involves the unwinding of the DNA double helix and the synthesis of two new complementary strands using the existing DNA strands as templates.
By the end of the S phase, each chromosome is duplicated, and the cell is prepared for cell division during the subsequent phases of the cell cycle.
In summary, the phase during the cell cycle in which DNA synthesis occurs is the S phase. It is a critical stage in the cell cycle where DNA replication takes place to ensure the accurate transmission of genetic information to daughter cells. * i guessed on number one since i didnt have any awnser choices.*
