Quizplus · Accepted Answer

A gene is a segment of a DNA strand that contains the instructions for making a specific protein or RNA molecule. It is the basic unit of heredity and is responsible for the traits and characteristics of an organism. Chromosomes are structures in the nucleus of a cell that contain genetic information, while double helix refers to the twisted ladder-like shape of DNA. Ribosomes are cellular structures responsible for protein synthesis, but they do not encode for proteins.
