Why DNA replication is called semiconservative?

DNA replication is called semiconservative because each new DNA molecule is composed of one original strand and one newly synthesized strand.

How DNA replication takes place?

DNA replication occurs by unwinding the double helix, then using each original strand as a template to synthesize a new complementary strand. Enzymes like DNA helicase, DNA polymerase, and ligase work together to unzip the DNA, add matching nucleotides, and join fragments, producing two identical DNA molecules

When does DNA replication start?

DNA replication starts during the S phase (Synthesis phase) of the cell cycle, just before a cell divides.
