MUSCLE PHYSIOLOGY

Detailed explanation-1: -So, the correct answer is ‘RNA molecule’

Detailed explanation-2: -There are many structural similarities between ATP and DNA nucleotides, with both being made of a pentose sugar, containing a phosphate and also (at least with some DNA nucleotides) containing an adenine base.

Detailed explanation-3: -Despite being similar in structure, ATP and DNA nucleotides are slightly different. Both contain a pentose sugar (a sugar containing 5 carbon atoms), and a nitrogenous base. A DNA nucleotide contains the sugar deoxyribose, whereas an ATP molecule contains the sugar ribose.

Detailed explanation-4: -Note:-When the nucleic acids-RNA and DNA is compared to the ATP, the RNA is more similar to the ATP than DNA, because RNA has the ribose sugar which resembles ATP, but DNA has deoxy-ribose sugar.

Detailed explanation-5: -ATP (adenosine triphosphate) is a nucleic acid compound consisting of three phosphate groups, ribose sugar, and an adenine nitrogenous base. Hence, ATP is also considered a nucleic acid molecule.
