Answer: Replication is called semiconservative because each of the original strand is is used as a template for the synthesis of a new strand
Explanation: DNA is a double-stranded helix containing two antiparallel strands that are complementary to each other.
Replication is the process of making identical copies of a DNA molecule. Before replication begins, the double-stranded DNA is first unwound by helicase so that each strand will serve as a template for new strand synthesis.
DNA replication is semiconservative because each DNA strand serves as a template for the synthesis of a new strand, producing two new DNA molecules each one with one new strand and one strand.
Saved and used in the new strand
