Document Summary
Many molecules set up a chemical message depending on how monomers bond together: nucleotides: phosphate group is bonded to 5 carbon sugar and a nitrogenous base, sugars: ribose in rna and deoxyribose in dna b. i. Rna is single stranded, has the capacity to be more reactive than a double stranded molecule: nitrogenous bases single ring structures, in nucleotides its. Cytosine, uracil is in rna and thymine is in dna. A condensation reaction forms a phosphodiester linkage (bond) between the phosphate group on the 5" carbon of one nucleotide and the oh group on the 3" carbon of another. Why can certain molecules only form with one another in dna and rna. In biochemistry, two biopolymers are antiparallel if they run parallel to each other but with opposite alignments. Polymerization of nucleic acids is an endergonic process catalyzed by enzymes. Energy for polymerization comes from phosphorylation of the nucleotides.
