WebSep 21, 2024 · Where does DNA replication start 3 or 5? DNA is always synthesized in the 5′-to-3′ direction, meaning that nucleotides are added only to the 3′ end of the growing strand. As shown in Figure 2, the 5′-phosphate group of the new nucleotide binds to the 3′-OH group of the last nucleotide of the growing strand. WebAug 27, 2024 · A new DNA strand only grows in the 5′ to 3′ direction because the enzyme that adds new bases to a growing strand requires a free 3′ OH group. Why does DNA replication start at 5 ends? DNA replication occurs in the 5′ to 3′ direction.
