The eukaryotic chromosomes are larger in size. Hence in order to overcome the limitation of DNA synthesis, multiple origins of replication are present in order to complete replication in a reasonable period of time.
In order for DNA polymerases to synthesize DNA they must encounter a free 3'-OH which is the substrate for attachment of the 5'-phosphate of the incoming nucleotide.
During replication the 3'-OH is supplied through the use of an RNA primer, synthesized by the primase activity. The primase utilizes the DNA strands as templates and synthesizes a short stretch of RNA generating a primer for DNA polymerase.
Synthesis of DNA proceeds in the 5'---->3' direction through the attachment of the 5'-phosphate of an incoming deoxy nucleosidetriphosphate (dNTP) to the existing 3'-OH in the elongating DNA strands with the concomitant release of pyrophosphate.
Initiation of synthesis, at origins of replication, occurs simultaneously on both strands of DNA.
DNA synthesis process then proceeds bidirectionally, with one strand in each direction being copied continuously and one strand in each direction being copied discontinuously.
The experimental support for this bidirectional mode of replication in the cells of higher eukaryotes was acquired by the fiber autoradiography of labeled DNAs got from mammalian cell cultures. When the replicating DNA extracted and isolated from eukaryotic cells are examined under the electron microscope, the clear "bubble" like structures extending from multiple replication origins are clearly visible.

DNA is a double helix. So during replication it unwinds and separates into two strands. One strand will be called the non-coding and the other will be called the coding strand. The non-coding strand will be the template for the new one.
The DNA splits up along the branches between the chains as a result of DNA helicase. Then free, single monomer units bind to their respective matches (A to T and C to G units) and reform to create two identical chains of DNA. The DNA monomer units are bound to the parent DNA strands using DNA Polymerase.
In industry this process is copied to produce large amounts of a sample of DNA. it is often during crime investigations to produce large amounts of a small sample.
Works like a negetive and it uses the negetive of DNA to make more DNA

Various DNA polymerases read the DNA template during replication of DNA. Various RNA polymerases read the DNA template during transcription.
Retro virus has reverse transcription in its replication cycle. In other words, rna is template for synthesis of dna. With dna virus, there is no reverse transcription in the replication cycle. Dna is the template for dna synthesis.
I believe it's called replication. not really sure though...
During DNA replication, the DNA molecule separates into two strands, then produces two new complementary strands following the rules of base pairing. Each strand of the double helix of DNA serves as a template, or model, for the new strand.
DNA serves as a template for transcribing mRNA.
