Which statement correctly compares nucleic acids and carbohydrates?
A) They both contain phosphorus, but only nucleic acids contain hydrogen.
B) They both contain carbon, hydrogen, and oxygen in a 1:2:1 ratio.
C) They both contain carbon, but only carbohydrates contain oxygen.
D) They both contain carbon, but only nucleic acids contain phosphorous.<\/p>\n\n\n\n

The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The correct answer is D) They both contain carbon, but only nucleic acids contain phosphorus.<\/strong><\/p>\n\n\n\n

Explanation:<\/strong><\/p>\n\n\n\n

Nucleic acids and carbohydrates are both essential biomolecules but have different structures, functions, and elemental compositions.<\/p>\n\n\n\n

1. Nucleic Acids:<\/strong><\/h3>\n\n\n\n

Nucleic acids, such as DNA and RNA, are composed of nucleotides, which consist of three main components: a phosphate group, a five-carbon sugar (either deoxyribose in DNA or ribose in RNA), and a nitrogenous base. The defining feature of nucleic acids is the presence of phosphorus<\/strong> in the phosphate group, which is critical in linking nucleotides together through phosphodiester bonds. Nucleic acids also contain the elements carbon, hydrogen, oxygen, and nitrogen.<\/p>\n\n\n\n

2. Carbohydrates:<\/strong><\/h3>\n\n\n\n

Carbohydrates are primarily composed of carbon, hydrogen, and oxygen in the general formula of (CH\u2082O)\u2099<\/strong>, where “n” represents the number of repeating units (monomers). Simple sugars like glucose, for instance, follow this 1:2:1 ratio of carbon to hydrogen to oxygen. Carbohydrates are classified into monosaccharides, disaccharides, and polysaccharides, depending on the number of sugar units. They serve as a primary energy source for organisms and play roles in structural functions.<\/p>\n\n\n\n

Comparison:<\/h3>\n\n\n\n
    \n
  • Common Elements:<\/strong> Both nucleic acids and carbohydrates contain carbon, hydrogen, and oxygen<\/strong>, but nucleic acids also contain nitrogen<\/strong> (in their nitrogenous bases) and phosphorus<\/strong> (in the phosphate group), whereas carbohydrates do not.<\/li>\n\n\n\n
  • Phosphorus Presence:<\/strong> Only nucleic acids contain phosphorus, making statement D correct. Carbohydrates lack phosphorus entirely.<\/li>\n\n\n\n
  • Carbon Presence:<\/strong> Both nucleic acids and carbohydrates contain carbon, one of the basic building blocks of organic molecules.<\/li>\n<\/ul>\n\n\n\n

    In conclusion, nucleic acids and carbohydrates share some elemental similarities, but nucleic acids are unique in their phosphorus content, while carbohydrates follow a simpler composition ratio.<\/p>\n","protected":false},"excerpt":{"rendered":"
