Knoxville is one of the hardest sections of the country in which to predict the weather. There is a topographical reason for Knoxvilleâs gentle climate. The Cumberland Plateau and Great Smoky Mountains shelter the Tennessee Valley, providing an annual average temperature of 56 degrees.
Each nucleotide consists of a sugar, a phosphate and a nucleic acid base. The sugar in DNA is deoxyribose. The sugar in RNA is ribose, the same as deoxyribose but with one more OH (oxygen-hydrogen atom combination called a hydroxyl).This is the biggest difference between DNA and RNA. Another difference is that RNA molecules can have a much greater variety of nucleic acid bases.he sugar in DNA is deoxyribose. The sugar in RNA is ribose, the same as deoxyribose but with one more OH (oxygen-hydrogen atom combination called a hydroxyl). This is the biggest difference between DNA and RNA.
DNA vs. RNA. Structurally RNA is different from DNA in consisting of ribose as pentose sugar and Uracil as the pyrimidine group. RNA is not double helix as DNA, but it forms similar helical structures by being wound back due to base pairing. Just as in DNA, the bases are hydrogen bonded in RNA in these helical regions. RNA exists as single helix in most regions. The pentose sugar in RNA is ribose and in DNA it is deoxyribose. Deoxyribse has one oxygen atom less on the 5â Carbon of the ribose sugar. Since RNA has few or no base pairs the Chargaff rule of equivalence of Adenine with Thymine and Cytosine with Guanine cannot be extended to DNA.
