why is DNA semi-conservative?

does it have something to do with two new strands are formed using the two molecules from the original DNA

  1. DNA is double strand, during transcription, they (the parents or original strands) separate into two single strands. Then the new strand will attach to each of the parent strand and form a new DNA molecule and because this new molecule consist half the parent and half the new strand, that's why it is semi-conservative.
