Begin by understanding the concept of DNA replication. DNA replication is the process by which a cell duplicates its DNA before cell division.
Learn about the semiconservative model of DNA replication. This model suggests that each of the two strands of the DNA helix serves as a template for the formation of a new complementary strand.
In semiconservative replication, each new DNA molecule consists of one original strand and one newly synthesized strand. This was demonstrated by the Meselson-Stahl experiment.
Contrast semiconservative replication with other models: conservative replication would mean the original DNA molecule is conserved and a completely new molecule is synthesized, while dispersive replication would involve segments of old and new DNA interspersed along each strand.
Recognize that the semiconservative model is the correct description of DNA replication in vivo, as it accurately reflects the process observed in cells.
