Dna Nucleotides And Bases Diagram. A deoxyribose 5 carbon sugar a phosphate group and a nitrogenous base figure 2. Names of nucleotides the five bases are adenine guanine cytosine thymine and uracil which have the symbols a g c t and u respectively.
Nucleotides found in dna differing only in the nitrogenous base. According to this model called as watson crick model the dna molecule is a double helix structure consisting of two long polynucleotide chains coiled round each other around an imaginary axis and running opposite to each other. Simply so what are the 5 nucleotides.
Its nitrogenous base represents one side of a base pair.
Rna contains uracil instead of thymine. Base pairing the nucleotides are identical except for the base which can be an adenine thymine guanine or cytosine. In rna the base uracil u takes the place of thymine. Nucleotides are made out of elements like nitrogen and carbon with a nitrogenous base a five carbon sugar component and a group.
