You all did a well-done job. But the correct answer is semi-consecutive theory because each helix has a copy of the old DNA, hence the term semi has explained.

The answer is semi-conservative because where the parent strand serves as a template for a new strand.

In DNA replication the semi-conservative theory is acceptable because during the replication process the old strand is conserved so as to synthesize the new strand.

Yeah, the semi conservative theory is correct, because the first theory used was this particular theory this was proved by scientists Matthew Meselson and Franklin Stahl using N14 and N15 heavy isotope.

I think the answer should be a dispersive theory.

According to the hypothesises and the knowledge of DNA there was two scientist who have done further experiments regarding DNA according to them first they have used the semi conservative method secondly the conservative method and finally it was prooved that the dispersive theory is the accepted hypothesis for DNA replication.

If anybody have a doubt means refer to the internet and books regarding DNA. Thank you.

Semi-conservative means half of the product is original while half of it is new. During replication, each original DNA strand acts as a template strand. Thus forming two new strands. In winding each new strand associates with one original strand.

I think the semi conservative theory is the true answer.

According to me most accepted theory of replication is semi conservative because it was practically proved by Mesolson and Stahl by using N14 and N15 heavy isotope.

In semi-conservative replication the parent strand serves as a template for the new strand that is, the daughter cell possesses both the parent genome and the new genome. This purely accounts for DNA replication.

I understood DNA is semi conservative theory because DNA made up half new strands & half old strands it is called semi conservative theory.
