Detailed explanation-1: -Nucleic acids are essential for all forms of life, and it is found in all cells. Nucleic acids come in two natural forms called deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Detailed explanation-2: -Correct answer: Nucleic acids are made up of nucleotides that contain a pentose sugar, a phosphate group, and a nitrogenous base. There are two types of nucleic acids; DNA and RNA. The difference between these two nucleic acids is their pentose sugar. DNA has deoxyribose whereas RNA has ribose sugar residues.

Detailed explanation-3: -Nucleic acids are large biomolecules that play essential roles in all cells and viruses. A major function of nucleic acids involves the storage and expression of genomic information. Deoxyribonucleic acid, or DNA, encodes the information cells need to make proteins.

Detailed explanation-4: -Nucleic acids such as DNA and RNA are the most important group of molecules because they are the genetic molecules of inheritance. Without DNA and RNA there would be no instruction manual for how to build the proteins of the body. It would be impossible to survive without DNA and RNA in our cells.
