What is the structure of DNA, and how does it differ from RNA?
1. Nucleotides form the repeating structural unit of nucleicacids.2. Nucleotides are linked together in a linear manner to forma strand of DNA or RNA.3. Two strands of DNA (and sometimes RNA) interact witheach other to form a double helix.4. The three-dimensional structure of DNA results from thefolding and bending of the double helix.
RNA is usually single stranded but a make bulge loops, internal loop, multibranch junctio, and stem loops. Contains Uracil instead of Thymine.
