5.Molecular Basis of Inheritance
normal
Okazaki fragments are synthesised on
A
Leading strands of $DNA$ only
B
Lagging strands of $DNA$ only
C
Both leading and lagging strands of $DNA$
D
Complementary $DNA$
Solution
(b) The strands of double helix run in opposite direction
[one strand-leading $(5' \to 3')$ and other one is lagging] lagging strand is synthesized in opposite direction
$(3' \to 5')$ and must be copied discontinuously resulting in okazaki fragments
(discovered by Reiji okazaki in $1968$)
