Which statement is best supported by the results of this experiment? a. several proteins are involved in dna replication b. the two dna strands are replicated in opposite directions c. cell division produces four identical dna strands d. dna replication is a semiconservative process

The correct answer would be D. DNA replication is a semiconservative process.

It shows the semi-conservative method of DNA replication.

In this method, the two strands get separated first and then each strand is used as a template for the synthesizing a new strand.

The two identical daughter DNA molecules are formed, each having one parental strand and one newly synthesized strand.

The same can be observed in the given figure that is, each of the two daughter DNA molecules is made up of blue (parental strand) and orange (newly synthesized) strands.
