Polymers {nucleic acid}| can have nucleotides connected by phosphodiester bonds. Nucleic acids are 10% of body dry weight.
structure
Phosphodiester-bond phosphate groups link pentose fifth carbon to next-pentose third carbon, called 5' to 3' linkage. Nucleotide nitrogenous bases are perpendicular to phosphodiester bond chain. Nucleotide ribose rings are parallel to phosphodiester bond chain. Phosphodiester bonds have no rotation. Nucleic acids have no branches.
information
Molecules encode genetic information in base sequences and replicate using strands as templates. DNA bases are adenine A, guanine G, cytosine C, and thymine T. DNA codes instructions for replication, transcription, and translation, to initiate and grow tissues and organs during development, to react to cell environment during development and in life, and to cycle over hours, days, months, and years.
