PURINE & PYRIMIDINE METABOLISM dr Agus Budiman. Nucleotide consists purine / pyrimidine base, ribose/deoxyribose and phosphates. Nucleotide consists purine.
Functions of Nucleotide: 1.Responsible for transmission of genetic informations 2. Act as energy currency 3.Carrier molecule for a broad spectrum of functional.
nucleotides are the activated precursors of nucleic acids. As such, they are necessary for the replication of the genome an adenine nucleotide, ATP,
