Answer:
The gene is a specific sequence of nucleotides within a DNA molecule that codes for a particular protein or functional RNA. It is a unit of heredity that is passed down from parent to offspring.
The chromosome is a structure in the cell nucleus that contains DNA. It is made up of DNA coiled around proteins called histones. Each chromosome contains many genes.
DNA (deoxyribonucleic acid) is a long, double-stranded molecule that contains the genetic instructions used in the development and functioning of all living organisms. It is composed of nucleotide units, with each unit made up of a sugar, a phosphate group, and a nitrogenous base. The four types of nitrogenous bases found in DNA are adenine, cytosine, guanine, and thymine. The specific sequence of these bases determines the genetic information stored in DNA.
In summary, the gene is a unit of heredity within the DNA molecule, the chromosome is a structure that contains DNA, and DNA is the molecule that stores genetic information.
