Question

What monomer is made up of a base, a sugar, and a phosphate group?
A : monosaccharide
B : nucleotide
C : phospholipid
D : amino acid

Answer 1

The answer is the option B. Nucleotide. Nucleotides are organic molecules formed by three units :one or more phosphate groups, a sugar with five carbons (ribose or deoxyribose) and a nitrogenous base. Nucleotids are the units that form the two nucleic acid polymers: DNA and the RNA.

Answer 2

My best opinion is B. Nucleotide because each nucleic corrosive monomer is made up of a sugar, a nitrogenous base, and a phosphate group.

Please correct any mistakes in my answer!! I'd be happy to fix it!! :)
