Question

28) The mechanism of DNA synthesis differs between the two new daughter strands during 28 replication. This is due to the fact that A) both RNA primers attach to the 3' end of the template strands, which are at B) the DNA strands run antiparall to each other and the DNA polymerase can only C) one RNA primer attaches to the 5' end of the parent strand and the other primer to D) both daughter strands can't extend toward the replication fork because there would opposite ends from each other. add nucleotides to the 3' end of the growing strand. the 3' end. not be room for two DNA polymerase enzymes.

Explanation / Answer

The mechanism of dna synthesis differs between the two new daughter strands during replication. this is due to the fact that the DNA strands run antiparallel to each other and the DNA polymerase can ony add nucleotides to the 3' end of the growing strand.

A DNA double helix is always anti-parallel, that means one strand runs in the 5' to 3' direction, while the other strand runs in the 3' to 5' direction. This makes two new strands are anti-parallel to their templates and DNA polymerase can synthesize DNA in only one direction by adding nucleotides to the 3' end of the growing DNA strand.
