Detailed explanation-1: -DNA replication is a semi-conservative process, because when a new double-stranded DNA molecule is formed: One strand will be from the original template molecule. One strand will be newly synthesised.
Detailed explanation-2: -DNA replication is semi-conservative because in the replication process the resulting DNA helix is composed of both a new strand and an old strand. This occurs because of the complementary base pairing, I.e. each nitrogenous base only pairs with its complementary pair.
Detailed explanation-3: -DNA replication uses a semi-conservative method that results in a double-stranded DNA with one parental strand and a new daughter strand.
Detailed explanation-4: -Semi-conservative mode of replication produces two copies, each containing one original strand and one new strand. On the contrary, conservative replication produces two new strands and would leave two original template DNA strands in a double helix.
