Question 3 (2 points)
why is dna replication (copying) described as semi-conservative?
1.)when dna copies itself, the new dna strand is made up entirely of the old
dna base pairs.
2.)when dna copies itself, it only copies some of its base pairs.
3.)when dna makes a copy of itself, the new dna strand does not have any of
the original dna bases pairs.
4.)when dna copies itself, the new dna strand has half of the bases of the
original strand.
