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.

Explanation: Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.
