Question

How many calories per gram for nucleic acids?

a) 0 calories.
b) 9 calories.
c) 7 calories.
d) 5.5 calories.

Answer 1

The caloric content of nucleic acids, which are primarily used to store and transmit genetic information, is not standardly defined but for estimation purposes, is considered to be about 4 calories per gram, with none of the given answer choices being correct.

Step-by-step explanation:

The caloric content of nucleic acids is not a common topic of discussion because we do not use nucleic acids as a direct source of calories in our diet.

However, for academic purposes, the caloric value is estimated by means of bomb calorimetry, similar to how other macronutrients are evaluated.

Although there is not a widely recognized standard caloric content for nucleic acids like there is for carbohydrates, proteins, and fats, some sources may estimate the value to be around 4 calories per gram, making none of the provided options (0, 9, 7, 5.5 calories) correct.

It's important to note that nucleic acids' primary function is to store and transmit genetic information, not serve as a significant source of energy.
