Question

the models show the chemical structures of a monosaccharide and a nucleotide. monosaccharide nucleotide complete the table to compare these structures. monosaccharide nucleotide is a building block of dna contains hydrogen has a phosphate group

Explanation:

Step1: Recall DNA building - blocks

DNA is made up of nucleotides, not monosaccharides. So for "Is a building block of DNA", monosaccharide is no and nucleotide is yes.

Step2: Analyze hydrogen - containing

Both monosaccharides and nucleotides have hydrogen atoms in their chemical structures. So both contain hydrogen.

Step3: Identify phosphate - group presence

Monosaccharides do not have a phosphate group. Nucleotides have a phosphate group as part of their structure.

Answer:

Monosaccharide	Nucleotide
Yes	Yes
No	Yes
