Compare the phosphates,sugars,and bases in DNA and RNA?

the difference between DNA and RNA is the type of sugar in the sugar-phosphate backbone that makes up the helix. The D in DNA stands for deoxyribose, which means it lacks an Oxygen bonded to the 2' Carbon atom in the 5-Carbon sugar. While the R in RNA is for ribose, a 5-C sugar. DNA is double stranded while RNA is single stranded (with few exceptions). Also, the nucleotides are slightly different in that DNA has Cytosine (C), Guanine (G), Adenine (A) and Thymine (T) as the bases and RNA has G, C, A and Uracil (U). A and G are known as purines (2-ring structures) and C, T, U are the pyrimidines (1 ring).
