Semi-conservative replication is the theory that states that during cellular division one of each of the parent strands is transmitted to each daughter cell along with one copy strand. This provides one original copy to each daughter cell. This theory is strongly supported by experimental autoradiographic evidence whereby a radioactive tracer in the parent DNA is diluted out by one-half in each subsequent division.
DNA replication is described as semi-conservative. The reason is because semi-conservative replication would produce two copies that each contained one of the original strands and one entirely new strand.
Semi conservative replication prevents mutations during DNA replication because it produces 2 copies that each contained 1 of the original strands and 1 entirely new strand.

DNA replication is the second part of inter-phase where the cell makes an exact copy of the DNA in its cell. Please see the answer to the related question below..
One strand is new, and one is old.
I'm not an expert on this subject but as I've learned, DNA is split into two replication forks where the complimentary base pairs and other backbones are added on, so ideally it would be 50% of the original strand in each daughter strand.
According to the conservative mode, of the two double helices formed one would be entirely of old material and the other entirely of new material. Thus the old parent double helix would be unchanged. According to the semi Conservative mode proposed by Watson and Crick, each strand of the two double helices formed would have one old and one new strand
The original DNA molecule is the template for the new DNA molecules.
The original DNA molecule is the template for the new DNA molecules.
DNA replication is said to be 'semi-conservative' because the two new daughter DNA molecules are "Half old" and "Half new". Half the original DNA molecule is saved, or conserved in the daughter molecules.
DNA replication is semi-conservative. This means that each newly synthesized DNA molecule is made up of one original (parental) strand and one newly synthesized strand. This was demonstrated by the Meselson-Stahl experiment in 1958.
Semi-conservative refers to the mechanism of DNA replication where each new DNA molecule contains one original strand and one newly synthesized strand. This process ensures that the genetic information is preserved and passed on accurately during cell division.
