Nucleic acid:
DNA is responsible for directing the cellular function. The nucleic acids are responsible for the storage of genetic information.
The DNA and RNA are the nucleic acids present in an organism. The DNA is the double stranded helix and comprises of sugars, nitrogenous base and a phosphate group. Deoxyribose is the sugar present along with 4 nitrogenous bases which are adenine, guanine, thymine and cytosine. These bases code for proteins which are responsible for carrying out range of activities such as cell growth, cell division and cell signalling.
RNA has ribose sugar and 4 nitrogenous base. Thymine is replaced by uracil in RNA. There are three types of RNA: rRNA, mRNA, and tRNA.

DNA (deoxyribonucleic acid) is a polynucleotide that directs cellular function.
There are two nucleic acids found in living beings, DNA and RNA. DNA is the genetic material in most organisms excluding some viruses that may contain RNA as their genetic material. DNA contains certain nucleotide sequences that encode proteins and are called genes. These proteins are important for the maintenance and functioning of the cell.
A DNA molecule contains four nucleotide bases, adenine, guanine, cytosine, and thymine. It is a double-stranded molecule. Uracil is a nitrogenous base in RNA molecules that are single-stranded in structure.
