Why a new DNA strand elongates only in 5' to 3' direction during DNA replication?
DNA polymerase IIl can add nucleotides only to the 3' end
DNA polymerase IIl begins adding nucleotides at the 5' end of the template;
The polarity of the DNA molecule prevents addition of nucleotides at the 3' end.
DNA polymerase can add nucleotides only to the 3' end:
