In this video you will learn DNA Replication In Eukaryotes and prokaryotic vs eukaryotic replication.
DNA replication in eukaryotes is a complex, highly regulated process that involves multiple enzymes, proteins, and other molecules. The process can be divided into three main stages: initiation, elongation, and termination.

Initiation:

1. The process begins with the unwinding of the DNA double helix at specific regions called origins of replication.
2. An enzyme called helicase unwinds the DNA, creating a replication fork.
3. Another enzyme, topoisomerase, relaxes the DNA molecule to prevent supercoiling.
4. A protein complex called the pre-replicative complex (pre-RC) assembles at the origin.

Elongation:

1. The pre-RC recruits an enzyme called DNA polymerase, which begins synthesizing new DNA strands.
2. DNA polymerase reads the template strands and matches nucleotides to them, forming new complementary strands.
3. An enzyme called RNA primase adds short RNA primers to the template strands, providing a starting point for DNA synthesis.
4. DNA polymerase extends the primers, synthesizing new DNA strands.

Termination:

1. When DNA replication is complete, the replication fork is dismantled.
2. An enzyme called DNA ligase seals the gaps between the newly synthesized DNA strands.
3. The resulting daughter DNA molecules are identical to the parent molecule.
