DNA replication is called semiconservative because each strand of the original double-helix appears in one daughter strand formed in replication.
During DNA replication, the original double-helix unwinds and each strand is used as a template to synthesize new complementary strands. After the synthesis, each old strand then forms a double-helix with its newly synthesized complementary strand.
Thus, the two double-helix that result from replication each consist of one strand from the original double-helix.
For example, if the original double helix is AB. During replication:
- A will separate from B
- A will synthesize a complementary copy B, new AB results
- B will synthesize a complementary copy A, new AB results
- The old AB remains but now in new double-helix
