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.
Which of the following descriptions is the best for a phospholipid?

b)A polar lipid molecule that is made nonpolar by the addition of a phosphate group.
c) A lipid molecule that consists of two fatty acids, glycerol and a phosphate group, and is amphitheatric.
d) A nonpolar lipid molecule that is made fully polar by the addition of a phosphate group so it can interact with water.
e) a polar lipid molecule that fully repels water through all its parts.
