Dna viruses essentially turn host cells into virus factories. Nucleic acid naturally occurring chemical compound that is capable of being broken down to yield phosphoric acid sugars and organic bases.

Many viruses also develop spikes made of glycoprotein on their envelopes that help them to attach to specific cell surfaces.
Virus nucleic acid function. The nucleic acids are vital biopolymers found in all living things where they function to encode transfer and express genes. Nucleic acids are the main information carrying molecules of the cell and play a central role in determining the inherited characteristics of every living thing. Viruses infect all types of life forms from animals and plants to microorganisms including bacteria and archaea.
They also use the host cells energy to feed themselves. Dna viruses have deoxyribonucleic acid. They invade the cells of host organisms and use the host cells machinery to create more viral capsules.
The virion capsid has three functions. The virus will then inject its nucleic acid into a host cell and reprogram. Rna is also essential for protein synthesis.
While the double stranded dna is responsible for this in prokaryotic and eukaryotic cells only a few groups of viruses use dna. Nucleic acids include dna and rna. The primary function of nucleic acids which in nature include dna and rna is to store and transfer genetic information.
Nucleic acid just as in cells the nucleic acid of each virus encodes the genetic information for the synthesis of all proteins. A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. These large molecules are called nucleic acids because they were first identified inside the nucleus of cells however they are also found in mitochondria and chloroplasts as well as bacteria and viruses.
The viral nucleic acid invades the nucleus and instructs the cell to make proteins which are assembled to produce further virus. These molecules are composed of long strands of nucleotides. 1 to protect the viral nucleic acid from digestion by certain enzymes 2 to furnish sites on its surface that recognize and attach adsorb the virion to receptors on the surface of the host cell and in some viruses 3 to provide proteins that form part of a specialized component that enables the virion to penetrate through the cell surface membrane or in special cases to inject the infectious nucleic acid into the interior of the host cell.
Nucleotides are composed of a nitrogenous base a five carbon sugar and a phosphate group. Nucleic acids consist of nucleotides which in turn are composed of a sugar a phosphate group and a nitrogenous base. Nucleic acids are macromolecules that store genetic information and enable protein production.
The viral nucleic acid either dna or rna has the genetic codes for the synthesis of proteins to produce new viruses i e virus s genome. When a virus finds a host cell the nucleic acid is injected into the host cell. The nucleic acid contains the virus s genetic material genome and codes for all the proteins needed to make a new virus.
