Why dna sythesis is directional (5’-3’)
Homework Answers
DNA Synthesis is directional ie DNA synthesis occurs in 5'-3' direction only. This because the DNA polymerase requires a free 3'- OH group because it adds the new nucleotides at the free 3' position with the help of RNA primase.

Explain the 5’-to-3’ directional activity of DNA polymerase. Please give an explanation for the inability of this enzyme to synthesize DNA in opposite direction (3’-to-5’).

If a DNA sequence was 5'-AATGCGGATTT-3' in one strand. What would be the sequence in the other strand? DNA chains are directional (like polypeptide chains) and anti-parallel. 5' and 3' are references to one end or the other. 5'-AATGCGGATTT-3' 3'-AATGCGGATTT-5' 3'-TTACGCCTAAA-5' 5'-TTACGCCTAAA-3' 3'-TTTAGGCGTAA-5'

Why does a new DNA strand elongate only in the 5' to 3' direction during DNA replication? The polarity of the DNA molecule prevents addition of nucleotides at the 3' en Replication must progress toward the replication fork. DNA polymerase can add nucleotides only to the free 3' end. DNA polymerase begins adding nucleotides at the 5' end of the template,
