What are the products of semiconservative replication for a double-stranded DNA molecule? What are the products of semiconservative replication for a double-stranded DNA molecule? Two double-stranded DNA molecules, one consisting of two parental strands and the other consisting of two daughter strands. Two double-stranded DNA molecules, each consisting of one parental strand and one daughter strand. One double-stranded DNA molecule consisting of one parental strand and one daughter strand. One double-stranded DNA molecule, consisting of two daughter strands.

Two double-stranded DNA molecules, each consisting of one parental strand and one daughter strand.

Explanation:

DNA replication is semi-conservative.

When DNA replication is to take place, the parent double-stranded DNA unwinds, and one strand is used as a template to make one daughter strand.

At the end of replication, two double-stranded DNA results, with one strand being a parent strand and the other being the newly sythesized daughter strand.

The semi-conservative mode of DNA replication was proven by the Meselson-Stahl experiment, in which DNA samples were tagged, and after replication, it was observed that the two resulting DNA both had one strand each from the parent strand.
