Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which would best distinguish a nucleic acid from a carbohydrate?
A
presence of carbon
B
presences of adenine
C
presence of fatty acids
D
presence of amino acids
Explanation: 

Detailed explanation-1: -Which would best distinguish a nucleic acid from a carbohydrate? presence of adenine. Which elements combine to form carbohydrates? Carbon, Hydrogen, and Oxygen.

Detailed explanation-2: -Nucleic acids contain nitrogen in the nitrogenous bases, which are components of nucleotides. Carbohydrates and lipids are made up of carbon, hydrogen and oxygen. They lack nitrogen.

Detailed explanation-3: -Which statement best compares a carbohydrate and a nucleic acid? A. The sequence of monomers in a carbohydrate stores genetic information, and the bonds in a nucleic acid store energy.

Detailed explanation-4: -Nucleic acids are long chainlike molecules composed of a series of nearly identical building blocks called nucleotides. Each nucleotide consists of a nitrogen-containing aromatic base attached to a pentose (five-carbon) sugar, which is in turn attached to a phosphate group.

Detailed explanation-5: -Nucleotides are linked to each other repeatedly in long strands by the formation of phosphate ester bonds. These long strands of bonded nucleotides make up a nucleic acid. Nucleic acids are polymers. They are composed of a chain of nucleotides, which are linked by phosphodiester bonds.
