DNA replication also works by using a DNA template, the DNA double helix unwinds during replication, exposing unpaired bases for new nucleotides to hydrogen bond to. Gene synthesis, however, does not require a DNA template and genes are assembled de novo. DNA synthesis occurs in all eukaryotes and prokaryotes, as well as some viruses. The ...
Biosynthesis, i.e., chemical synthesis occurring in biological contexts, is a term most often referring to multi-step, enzyme-catalyzed processes where chemical substances absorbed as nutrients (or previously converted through biosynthesis) serve as enzyme substrates, with conversion by the living organism either into simpler or more complex ...
Thymidylate synthase (TS) plays a crucial role in the early stages of DNA biosynthesis. [11] DNA damage or deletion occur on a daily basis as a result of both endogenous and environmental factors. Such environmental factors include ultraviolet damage and cigarette smoke that contain a variety of carcinogens. [12] Therefore, synthesis and ...
Nucleic acid metabolism is a collective term that refers to the variety of chemical reactions by which nucleic acids (DNA and/or RNA) are either synthesized or degraded.. Nucleic acids are polymers (so-called "biopolymers") made up of a variety of monomers called nucleo
Biosynthesis, the creation of an organic compound in a living organism, usually aided by enzymes Photosynthesis, a biochemical reaction using a carbon molecule to produce an organic molecule, using sunlight as a catalyst; Chemosynthesis, the synthesis of biological compounds into organic waste, using methane or an oxidized molecule as a catalyst
DNA exists in many possible conformations that include A-DNA, B-DNA, and Z-DNA forms, although only B-DNA and Z-DNA have been directly observed in functional organisms. [14] The conformation that DNA adopts depends on the hydration level, DNA sequence, the amount and direction of supercoiling, chemical modifications of the bases, the type and ...
