DNA replication fork. Diagram showing the cyclic sequence (right) for replication of DNA (deoxyribonucleic acid). Details of the DNA are at left. At right (stage 1), the DNA has been split (orange and green area) into a leading (left) and lagging (right) strand. DNA replication (yellow and orange structures) occurs continuously on the leading strand, but discontinuously on the lagging strand. The resulting Okazaki fragment grows until it meets (stage 3) and is joined with the previous fragment and is released from the sliding clamp (blue, stage 4). In stages 5 and 6, the new RNA primer (pink, formed in stage 2) starts a new Okazaki fragment.
