Answer:
The correct answer will be- the first part of the sequence which was added first.
Explanation:
DNA replication is an energy-dependent process which synthesizes a new DNA molecule from the existed DNA strands of the organisms.
The process is mediated by many enzymes, one of which is DNA polymerase which adds new nucleotides to the 3' end and replication appears to be favoured in the direction of the 5' to 3' direction.
Since the replication takes place in the 5' to 3' direction therefore, the 5' end represents the part of the sequence which was added first.
