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.
Three of the nitrogenous bases are the same for both RNA and DNA: guanine, adenine, and cytosine. Thymine, the fourth base pair found in DNA, is replaced by uracil in RNA. DNA has deoxyribose sugar while RNA has ribose sugar. The deoxyribose sugar has one less oxygen atom than the ribose sugar.ere are some major â¦ differences between RNA and DNA: With the exception of a few viruses, RNA is a single-stranded molecule while DNA is double-stranded. The two DNA chains are connected by hydrogen bonds between nitrogenous bases. DNA can is replicated during cell division; RNA is not.
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.
