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: -Adenine is a type of purine. Structure of DNA. Most DNA is found inside the nucleus of a cell, where it forms the chromosomes.
