If you could add a colored label to each strand of a DNA molecule then follow the colored label in the DNA molecules that result from replication of the original DNA, in the two new molecules you would see:
A) colored label on both strands of one of the DNA molecules and no label on either strand of the other DNA molecule.
B) colored label in one strand only of each of the DNA molecules.
C) no colored label in either DNA molecule.
D) a zebra-striped pattern of some patches with color and some patches without on each molecule.
E) colored label on both stands of both DNA molecules.

DNA replication is semi-conservative, meaning each new DNA molecule consists of one original strand and one newly synthesized strand. Therefore, if a colored label were added to the strands of the original DNA molecule, after replication, each new DNA molecule would have one labeled strand (from the original DNA) and one unlabeled strand (the newly synthesized strand).
