... four bases of DNA. The organic bases can be one of the five different bases: Adenine, Guanine, Cytosine, Thymine, and Uracil. The bases found in DNA are: C, T, A, and G. The bases found in RNA are: U, A, G, and C. 2.4.3 2 Outline how the DNA nucleotides are linked together by covalent bonds into a single strand. The nucleotide can be linked together by a covalent bond between the phosphate of one nucleotide and the sugar of another. This way the sugar and phosphate from the "backbone" of the nucleic acid with the nitrogen base sticking out. Covalent bonds are formed between the phosphate and (deoxy)ribose and a nitrogen base attached to every sugar. Three nucleotides represent a codon, which typically codes for an amino acid.
