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.
Who is credited with the discovery of the structure. RNA is single stranded,rna has uracil instead of thymine, rna has ribose sugar while dna has deoxyribose,rna is found everywhere in the cell and dna is only in the nucleus. Name three differences between dna & rna. helicase-the enzyme-unzips the two strands of a dna molecule at the hydrogen bonds between the paired nitrogen bases. what is the first step of dna replication and what enzyme is involved in this step.
