- during DNA replication, a complementary strand of dna is made from each original DNA strand. Thus, if a portion of the original strand is CCT AGC, then what will the new strand beWhen DNA is replicated, two new DNA double helices areformed, each consisting of one parental strand and onenew, daughter strand. For this reason, DNA replication iscalled________ .List the differences and similarities in the way the twodaughter strands of DNA are synthesized at a replicationfork.
