WebNucleic acids are the long chain bio-polymers with complex structure. They serve as transmitters of genetic information. There are two types of nucleic acids they are Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA). Nucleic acids are built up by monomeric units called nucleotides. They contain a polyphosphate ester chain. … WebKevlar is similar in structure to nylon-6,6 except that instead of the amide links joining chains of carbon atoms together, they join benzene rings. The two monomers are benzene-1,4 …
