3. Shown below is a double stranded DNA. Replicate this DNA fragment and show the products formed from this replication. Remember, in replication, each strand is copied into a new daughter strand. In your answer, indicate which strands are the new daughter strands (mark with D) and which strands are the already existing parent strands (mark with P as shown below). Label the 5’ and 3’ ends of all DNA. HINT: You should have 2 double-stranded DNA fragments after replication....
