Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.
Option A: Carbohydrate
Carbohydrates are also known as hydrates of carbon that consist of carbon (C), hydrogen (H), and oxygen (O) only. Additionally, the chain of carbohydrates includes an aldehyde or a ketone group along with a hydroxyl group.
Option B: Lipid
Lipids are the long hydrocarbon chains that are the polymers of glycerol with at least one hydrophobic end.
Option C: Protein
Proteins are the long chain of monomer amino acids. The structure of a protein includes an amino group (NH3+), a carboxyl group (COOH), an H atom, and an ‘-R’ group.
Option D: Nucleic acid:
The nucleic acids are polynucleotide molecules consisting of nucleotides as monomeric forms. The structure of nucleotides includes a phosphate group, a pentose sugar, and a nitrogenous base. The nitrogenous base in the nucleotide may be a purine or a pyrimidine.
The proposed structure does not fulfill the requirement of any of the mentioned structures. Additionally, the given macromolecule is highly unstable as the octet for ‘N’ has not been fulfilled.
