The lytic cycle of viral replication is most likely to damage host cells immediately. In this cycle, the virus infects the host, takes over its cellular machinery to produce new viral particles, and ultimately causes the host cell to burst (lyse), releasing the newly formed viruses. This immediate destruction of the host cell results in significant damage and can lead to cell death. In contrast, the lysogenic cycle integrates the viral genome into the host's DNA, allowing the virus to replicate without immediately harming the host.
A virus is protected from damage by its protein coat, which helps shield its genetic material. Additionally, viruses can enter host cells to hijack their machinery for replication and evade the immune response. Some viruses also have mechanisms to repair any damage that may occur during replication.
DNA replication and transcription occur in the nucleus of eukaryotic cells. In prokaryotic cells, replication and transcription occur in the cytoplasm.

In prokaryotic cells, which have a single circular chromosome, replication initiates at a single origin of replication and proceeds bidirectionally until the entire chromosome is copied. In contrast, eukaryotic cells have multiple linear chromosomes that replicate from multiple origins of replication simultaneously. The linear nature of eukaryotic chromosomes poses challenges during replication, such as the need to overcome end-replication problem and preserving telomeres.
You would expect to find more replication origins in developing embryo cells compared to adult cells. This is because embryonic cells undergo rapid proliferation and need multiple origins of replication to ensure that DNA is replicated efficiently to support growth and development. In contrast, adult cells typically have a more stable and differentiated state, resulting in slower division rates and fewer replication origins.

Because if it didn't happen then only one of the two cells would get DNA and the other would die immediately

No time is required -- they are fully mature and ready to divide immediately after separation if conditions are right.
Any form of biological reproduction, whether sexual or asexual, is going to involve the replication of DNA. You can't have new cells without new DNA.
Replication typically occurs in the nucleus of a eukaryotic cell and the cytoplasm of a prokaryotic cell. In eukaryotic cells, DNA replication takes place in the nucleus, while in prokaryotic cells like bacteria, replication occurs in the cytoplasm.

Red blood cells are the least sensitive to ionizing radiation damage because they lack a nucleus and are unable to repair DNA damage caused by radiation exposure. This also makes them unable to undergo cell division or replication.
Cancer is the disorder characterized by abnormal replication of cells that can lead to the formation of tumors.
The cell is most likely in the G1 phase of the cell cycle. During G1 phase, the cell prepares for DNA replication in the S phase. Cells with half the amount of DNA compared to others have likely already undergone DNA replication and are in the early stages of the cell cycle.
DNA replication takes place in the nucleus of human cells.
