Web9 mrt. 2014 · 4,181. When a textbook states that DNA can only be replicated in the 5' to 3' direction, it is referring to the synthesis of DNA. Each strand of DNA has a 5' end and a 3' end. In order to make that strand longer, you could imagine adding new DNA to the 3' end of the strand or to the 5' end of the strand. As it turns out, DNA polymerases can ... Web29 jul. 2024 · DNA replication always happens in the 5 to 3 direction because it is antiparallel, which explains why the lagging strand exists. Okazaki fragments are brief sequences of DNA nucleotides that are synthesized intermittently and later joined by the enzyme DNA ligase to form the lagging strand during DNA replication.
