Answer 1

Continuous	Discontinuous
(a) One stand of DNA is synthesised as a continuous strech in the 5′ —>3′ direction.	(a) Short stretches  are synthesised in the 5’—>3′ direction from replication fork
(b) The template strand of DNA strand is with 3’—>5′ polarity.	(b) The DNA strand with 5′ —> 3′ polarity is the template strand  for this.
(c) No need of enzyme ligase (for joining)	(c) DNA ligase  enzyme is required  for joining short stretches.
(d) There is no need for primers.	(d) There is need for primers.
