Explain the similarities and differences between DNA and RNA?

Similarities: Consist of chains of nucleotides, and have a similar compound make up, 3/4 same nitrogenous bases Differences: DNA is almost always found in a long helix shape RNA takes a variety of forms Each nucleotide in a DNA chain contains a deoxyribose, a phosphate group, and one of 4 bases: ATGC Each nucleotide in an RNA chain contains a ribose, a phosphate and one of the 4 bases: AUGC DNA stores the hereditary information that is responsible for inheriting traits in eukaryotes and prokaryotes and in viruses RNA is the hereditary molecule of some viruses
