A cistron (also known as a gene) is defined as a sequence of bases in DNA which contains the information for one functional polypeptide.

The other options are:
A) A codon is the sequence of three nucleotides that specifies a particular amino acid or termination signal during translation. 
C) A polysome is a complex of several ribosomes translating a single mRNA molecule. 
D) A polycistronic message is an mRNA molecule that encodes multiple polypeptides. 
E) An operon is a cluster of genes under the control of a single promoter, often involved in a common biological pathway.
