What are three major differences between rna and dna?

1. DNA is double stranded, while RNA is single stranded

2. DNA contains the sugar deoxyribose; while RNA containers the sugar ribose

3. The four nitrogenous bases that are a part of DNA are guanine, cytosine, adenine, and thymine; in RNA, the four nitrogenous bases are guanine, cytosine, adenine, and uracil (the uracil in RNA replaces the thymine in DNA)

Hope this helps :)
