Explanation:
Difference between Leading and Lagging Strand:
During DNA replication, the leading strand and the lagging strand are synthesized differently due to the antiparallel nature of DNA.
Leading Strand:
Synthesized continuously in the 5’ to 3’ direction.
DNA polymerase adds nucleotides in the same direction as the replication fork movement.
Requires only one RNA primer at the origin of replication.
Fewer Okazaki fragments.
Lagging Strand:
Synthesized discontinuously in the 5’ to 3’ direction.
DNA polymerase adds nucleotides away from the replication fork movement.
Requires multiple RNA primers along the length of the strand.
Composed of Okazaki fragments that are later joined by DNA ligase.
What Happens if DNA Ligase (G) Malfunctions?:
DNA ligase plays a critical role in sealing the gaps between Okazaki fragments on the lagging strand during DNA replication.
If DNA ligase malfunctions:
Incomplete DNA Repair: The gaps between Okazaki fragments would remain unsealed, leading to incomplete DNA strands.
Genetic Mutations: Unrepaired gaps could result in genetic mutations or deletions.
Cell Viability: Proper DNA repair is essential for cell viability and accurate transmission of genetic information.
