A co-ordinated unit which controls the genetic expression is called as a/an
Open in App
Solution
The correct option is C Operon
Cistron: Is a section of a DNA or RNA molecule that codes for a specific polypeptide in a protein synthesis.Recon: In a cistron, the recombinational units may be more than one. Thus, the smallest unit capable of undergoing recombination is called as a recon.Muton: It may be defined as, "the smallest unit of DNA which may be changed is the nucleotide''. Therefore, cistron is the largest unit in size followed by recon and muton. This can be explained that a gene consists of several cistron, a cistron contains many recons and a recon contains a number of mutons. Operon: It is a unit of genetic material that functions in a co-ordinated manner by means of an operator, a promoter and one or more structural genes that are transcribed together.Thus, the correct answer is option C.
