Okazaki fragments are :

Explanation

Okazaki fragments During DNA replication, the new strand elongation occurs in opposite directions, as the two strands of the DNA are antiparallel. On the leading strands, a continuous synthesis of new strand occurs while on the other strand (5. - 3. strand) discontinuous synthesis occurs. These discontinuous pieces of new DNA strands are called Okazaki fragments which join by DNA ligase to form the continuous strand
