What are the 4 functions of nucleotide​
Leni [432]

Nucleotides play different roles such as being the building blocks of nucleic acids, energy storage, cellular signaling, enzymatic cofactors, etc.

  • Nucleotides are the building blocks of nucleic acids (either DNA or RNA).

  • These molecules (nucleotides) are composed of one pentose sugar, a nitrogenous base, and one or more phosphate groups.

  • In DNA, there are four types of nucleotides, each containing one different nitrogenous base (i.e., Adenine, Guanine, Cytosine and Thymine).

  • Adenosine triphosphate (ATP) is a nucleotide that represents the energy coin of the cell, which is used to carry out different metabolic functions (e.g., growth, differentiation, reproduction, etc).

In conclusion, nucleotides play different roles such as being the building blocks of nucleic acids, energy storage, cellular signaling, enzymatic cofactors, etc.
