Q: Which of the following constitute to form a gene?
  • A. Polynucleotides
  • B. Hydrocarbons
  • C. Lipoproteins
  • D. Lipids
Correct Answer: Option A - Gene is the basic physical and functional unit of heredity. A polynucleotide molecule is a biopolymer composed of 13 or more nucleotide monomers covalently bonded in a chain. DNA and RNA are examples of polynucleotides with distinct biological function. Polynucleotides are formed by covalent linkage between the phosphate of one nucleotide and sugar of another, resulting in phosphodiester linkages.
