Final answer:
Both DNA and RNA contain monosaccharides within their structures. DNA includes the pentose sugar deoxyribose, and RNA includes the pentose sugar ribose. The correct answer is b) DNA and d) RNA.
Step-by-step explanation:
The question asks which of the given substances contains a monosaccharide as part of its structure. To address this, it is crucial to understand that a monosaccharide is the most basic form of carbohydrates, often called simple sugars.
Monosaccharides include glucose, fructose, and galactose, which are hexose sugars with six carbon atoms, and ribose and deoxyribose, pentose sugars with five carbon atoms. These sugars are fundamental units that combine to form more complex carbohydrates.
Looking at the options given: a) Triglyceride is a lipid and does not contain monosaccharides. b) DNA (deoxyribonucleic acid) contains the pentose sugar deoxyribose as part of its structure, representing the 'D' in DNA. c) Cellulose is a polysaccharide, consisting of many glucose molecules linked together. d) RNA (ribonucleic acid) contains the pentose sugar ribose.
Therefore, both DNA and RNA contain monosaccharides (the pentose sugars deoxyribose and ribose, respectively) as part of their structures. The correct answer is b) DNA and d) RNA.
