Homework Help: intro chemistry college

State two differences between DNA and RNA.
we did not study this at all, so far I see that DNA has several million nucleotides, the smaller RNA only has several thousand of them. the second thing I noticed is that they both have a base,a five carbon sugar and a phosphate group DNA has adenine and guanine and two pyrimidines, cytosine, and thymine. RNA contains the same bases except thymine is replaced by uracil. Do you think that would be what they are asking for or is there differences in the acids also? thanks

no they have them listed under teriarity bands of peptides they state that they are side chains that are nonpolar that they piush away from an aqueos enviroment for hydropobic, like push away. the hydophilic has polar side chains that pull toward the aquous enviroment, but she is asking for examples. thanks.
