Q. During replication of DNA, Okazaki fragments are formed in the direction of
A) 3’$\rightarrow$5’
B) 5’$\rightarrow$3’
C) 5’$\rightarrow$5’
D) 3’$\rightarrow$3’
Explanation
Okazaki et. Al, (1968) suggested that during DNA replication only one strand shows a continuous replication (leading strand), while other strand (lagging strand) replicates in a discontinuous manner, $i.e.,$ synthesises short fragments called Okazaki fragments. Both the strands synthesise new strand in 5’ $\rightarrow$3’ direction (of new strand).
