What are the differences between DNA and RNA

There are 4 main differences, the first being that DNA is in a double helix structure much like two pieces of string wrapped together. RNA, on the other hand, is single-stranded. The second difference is in the pentose sugar that both of the two structures have. Deoxyribonucleic acid (DNA) contains the sugar deoxyribose and Ribonucleic acid (RNA) contains the sugar ribose. One of the 4 base pairs also differs in RNA - Cytosine and Guanine are common in both, however in RNA, Adenine bonds to the base Uracil instead of Thymine in DNA. Apart from structural differences they also have functional differences; DNA codes for proteins inside an organism. RNA has a variety of purposes, some of which include; messengers (mRNA), protein builders (tRNA)
