34/ Which of the fokwang statements best explans the mecharem for DNA replication? DNA replication is reductive, because half the total DNA present in copied DNA replication is semi-conservative, because each DNA strand serves as a template during replication DNA replication is dispersive, because the two resulting DNA molecules are mixtures of parent and daughter DNA DNA replication is conservative, because one resulting molecule is identical to the original and the other consists of two new strands
