Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms and some viruses. The main role of DNA molecules is the long-term storage of information. DNA is often compared to a set of blueprints or a recipe, since it contains the instructions needed to construct other components of cells, such as proteins and RNA molecules. The DNA segments that carry this genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information. Chemically, DNA consists of two long polymers of simple units called nucleotides, with backbones made of sugars and phosphate groups joined by ester bonds. These two strands run in opposite directions to each other and are therefore anti-parallel. Attached to each sugar is one of four types of molecules called bases. It is the sequence of these four bases along the backbone that encodes information. This information is read using the genetic code, which specifies the sequence of the amino acids within proteins. The code is read by copying stretches of DNA into the related nucleic acid RNA, in a process called transcription. Within cells, DNA is organized into structures called chromosomes. These chromosomes are duplicated before cells divide, in a process called DNA replication. Eukaryotic organisms (animals, plants, and fungi) store their DNA inside the cell nucleus, while in prokaryotes (bacteria and archae) it is found in the cell's cytoplasm. Within the chromosomes, chromatin proteins such as histones compact and organize DNA. These compact structures guide the interactions between DNA and other proteins, helping control which parts of the DNA are transcribed.
definitly with the help of enzymes is not replication wouldn't be able to occur.
Enzymes
Anabolic - Term describing enzyme-catalyzed reactions in a cell that involves the synthesis of complex molecules out of simpler subunits and which uses energy.(From Sparknotes)
Without enzymes, DNA replication would not occur. DNA Polymerases are responsible for catalysing the bonding of nucleotides, and for replacing primers. These functions are essential for DNA replication.

Denaturing in the sense that proteolytic enzymes reduce proteins to their amino acid subunits.

genomic replication, or DNA replication, is performed by multiple enzymes that together are called a replicase. This replication takes place within the nucleus of a cell
