What this topic is really about
Glucose is a monosaccharide because it is a simple sugar unit that cannot be further hydrolyzed into smaller carbohydrate molecules. In contrast, disaccharides like sucrose consist of two monosaccharide units joined together, while polysaccharides contain long chains of these units.
Messenger RNA (mRNA) carries the genetic blueprint from DNA to ribosomes, where it serves as the direct template for protein synthesis during translation. DNA replication, on the other hand, is the process of copying DNA and is catalyzed by DNA polymerases rather than mRNA.

An exam-style question, fully explained
Glucose is a:
- Identify what the question tests: Glucose is a:.
- Glucose is a monosaccharide because it is a simple sugar unit that cannot be further hydrolyzed into smaller carbohydrate molecules.
- In contrast, disaccharides like sucrose consist of two monosaccharide units joined together, while polysaccharides contain long chains of these units.
Traps the examiner sets
- Selecting three peptide bonds is a common error, as that would link four amino acids to form a tetrapeptide.
- Distractor A is incorrect because ribose is the sugar component of RNA, containing a hydroxyl group at that same position.
