Question

Why does dna synthesis only proceed in the 5' to 3' direction?

Answer 1

Heya Mate..........

Here is your answer..............

______________________________________

DNA replication goes in the 5' to 3' direction because DNA polymerase acts on the 3'-OH of the existing strand for adding free nucleotides. ... dNTP is a nucleotide which has two additional phosphates attached to its 5' end.

Thanks.............

Answer 2

Because dna polymerase can replicate only in one direction that is 5' to 3'
