  1. Question 1

    Q1. During cellular work, ATP is used as an energy currency. How does an ATP molecule structurally differ from a standard monomeric nucleotide of DNA?

    • A) Number of phosphate groups
    • B) Type of nitrogenous base
    • C) Presence of a sugar
    • D) Ability to form bonds
