Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following monomers are repeatedly joined together to form a nucleic acid like DNA or RNA?
A
amino acids
B
nucleotides
C
fatty acids
D
polysaccharides
Explanation: 

Detailed explanation-1: -A nucleic acid is a polymeric macromolecule made up of repeated units of monomeric ‘nucleotides’ composed of a nitrogenous heterocyclic base which is either a purine or a pyrimidine, a pentose (five carbon) sugar (either ribose or 2′-deoxyribose), and one to three phosphate groups.

Detailed explanation-2: -DNA monomers are called nucleotides.

Detailed explanation-3: -Nucleotides. DNA and RNA are polymers (in the case of DNA, often very long polymers), and are made up of monomers known as nucleotides. When these monomers combine, the resulting chain is called a polynucleotide (poly-= “many").
