Okazaki Fragments are short segments of DNA that are synthesized on the lagging strand during DNA replication. They are named after the Japanese scientists Reiji and Tsuneko Okazaki, who discovered them in the 1960s. These fragments are typically 100 to 200 nucleotides long and are formed because DNA polymerase can only add nucleotides in a 5' to 3' direction. During replication, the leading strand is synthesized continuously, while the lagging strand is made in pieces due to the antiparallel nature of DNA. After the Okazaki Fragments are created, they are later joined together by the enzyme DNA ligase to form a continuous strand, ensuring the integrity of the newly replicated DNA.
