What is a gene in genetics?

  1. a monosaccharide sugar that has several forms

  2. a segment of DNA that is involved in producing a polypeptide chain

  3. a gasoline substitute consisting of 90% gasoline and 10% grain alcohol from corn

  4. the state of matter distinguished from the solid and liquid states by relatively low density and viscosity

The correct answer is: a segment of DNA that is involved in producing a polypeptide chain

A gene is a section of DNA that contains the instructions for creating a specific protein or functional RNA molecule. It is not a sugar or a fuel substitute, nor is it a state of matter. The other incorrect options do not accurately describe a gene or its function in genetics.
