e. All of the above.

Explanation:

a) Nucleotide play important role in metabolic pathways and serve as energy carriers in the form of nucleoside triphosphate ATP and GTP.

b) Nucleotide being part of the structure of enzyme cofactor serve in supporting the chemical reactions.

c) nucleosides and nucleotides are building blocks for the genetic code and cellular energy currencies.

d) they are essential for the replication of genome (DNA synthesis), Nucleotide are also used in the PCR reactions for amplification and strand synthesis.
