A sequence of bases in DNA which contains structural information for one functional polypeptide is called a (an)

Question

Quizplus · Accepted Answer

A cistron refers to a segment of DNA that contains the information for a single functional polypeptide or protein. It contains the sequence of bases that make up the coding region for the mRNA transcript which is translated into a protein. The term "codon" refers to a sequence of three nucleotides that codes for a specific amino acid in a protein. "Operator" and "operon" refer to elements in bacterial DNA that regulate gene expression, while "polycistronic message" refers to a single mRNA transcript that contains the coding regions for multiple genes.  So, among the given choices, cistron is the best answer.
