Answer» Heya..!
Leading strand
- it is REPLICATED strand of DNA which grows continously without any gap.
-It doesnot require DNA ligase for its growth.
-the direction of growth of leading strand is 5'--->3'
-Only a single RNA primer is required.
-Formation of leading strand is quite rapid.
-it's template OPENS in 3'--->5' direction.
-Formation of leading strand begins IMMEDIATELY at the beginning of replication.
Lagging strand
-Lagging strand is a replicai strand of DNA which is formed in short segments called okazaki fragments.Its growth is discontinuous.
-DNA ligase is required for joining okazaki fragments.
- The direction of growth of lagging strand is 3'-->5' though in each okazaki fragment it is 5'--->3'
-Starting of each okazaki fragment requires a New RNA.
-Formation of lagging strand is slower.
-its template opens in 5'---->3' direction.
-Formation of lagging strand begins a bit later than that of leading strand.
HOPE THIS HELPS YOU.
