The enzyme that catalyzes DNA replication is DNA Polymerase. ... This enzyme first binds to a specific site on the DNA known as the origin of ... a single origin on their chromosome while eukaryotes have several on each of ... This is similar to what happens when your coiled telephone cord gets overwound and forms knots.
Two replication forks are produced when DNA denatures at an origin, allowing for bidirectional DNA synthesis. Each fork moves in opposite directions along the DNA strand, with one moving towards the replication fork and the other moving away from it.
The human chromosomes have hundreds of origins of replication where the DNA unwinds and replication begins. These origins are specific DNA sequences that mark the starting points for the replication process by recruiting the necessary enzymes and proteins. Replication occurs bidirectionally from each origin, ensuring that the entire chromosome is faithfully duplicated.
DNA molecules separate or unwind at specific sites known as replication origins. These regions serve as starting points for the enzyme complex that unwinds the DNA strands, creating a replication fork. DNA replication occurs bidirectionally from each origin, with the two strands being replicated simultaneously.
During DNA replication, the two DNA strands separate at the origin of replication, forming a replication bubble. Enzymes like helicase unwind the DNA strands, while DNA polymerase replicates each strand by adding complementary nucleotides. This process ensures that each newly formed DNA molecule contains one original strand and one newly synthesized strand.
They reproduce by Process called BINARY FISSION Binary fission begins with DNA replication. DNA replication starts from an origin of replication, which opens up into a replication bubble (note: prokaryotic DNA replication usually has only 1 origin of replication, whereas eukaryotes have multiple origins of replication). The replication bubble separates the DNA double strand, each strand acts as template for synthesis of a daughter strand by semiconservative replication, until the entire prokaryotic DNA is duplicated. After this replicational process, cell growth occurs. Each circular DNA strand then attaches to the cell membrane. The cell elongates, causing the two chromosomes to separate. Cell division in bacteria is controlled by the FtsZ, a collection of about a dozen proteins that collect around the site of division. There, they direct assembly of the division septum. The cell wall and plasma membrane starts growing transversely from near the middle of the dividing cell. This separates the parent cell into two nearly equal daughter cells, each having a nuclear body. The cell membrane then invaginates (grows inwards) and splits the cell into two daughter cells, separated by a newly grown cell plate.

At each origin of replication, the DNA helicase unwinds the double helix, creating two replication forks where DNA synthesis can occur. This process is followed by the binding of single-strand DNA-binding proteins to stabilize the separated strands and the initiation of DNA synthesis by DNA primase, which synthesizes short RNA primers for DNA polymerase to extend from.

Repetition is something that is being repeated, for instance.. The same thing happens during each experiment. And replication is having a double of something.

Because in eukaryote the DNA is antiparallel, so the polymerase has to go in one direction up the leading strand and in the reverse direction down the lagging strand. Of course, two polymerase at the same time.
each new DNA double helix consists of one old strand and one new strand
