Many scientists of the day actually thought it was protein because there are 20 different amino acids for building a protein polymer, while DNA polymers are made of only four nucleotidebases.

What is the role of DNA? Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things. All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage ofinformation.

What is DNA made of? DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, orgenetic code.

Do nucleic acids carry genetic information? DNA and RNA are long linear polymers, called nucleic acids, that carry information in a form that canbe passed from one generation to the next. Genetic information is stored in the sequence of bases along a nucleic acid chain.

How DNA is a genetic material? They are basically DNA inside a protein coat. To reproduce, a virus must insert its own genetic material into a cell (such as a bacterium). DNA was the molecule they identified. This confirmed that DNA is the genetic material.
