A) double helix segments
B) satellite segments
C) Komberg segments
D) Okazaki segments
Correct Answer: D
Solution :
During DNA replication, there occur a simultaneous continuous synthesis of DNA at both the strands of template in \[5\to 3\]direction of newly synthesized strand. Okazaki et al, (1968) suggested that it is only one strand which shows such a continuous replication (called leading strand) while other strand replicates in a discontinuous manner ie, synthesizes short fragments called Okazaki fragments. This discontinuous strand is called lagging strand.
