Which feature is least likely to be associated with the lac operon?
A) repressor
B) master genes
C) operator
D) promoter
E) lactose
Lac Operon
A group of genes in bacteria controlled by a single promoter, involved in lactose metabolism and regulation of gene expression.
Master Genes
Master genes are genes that control the activity of other genes, playing a critical role in regulating development and differentiation within living organisms.
Repressor
Transcription factor that slows or stops transcription.

Final Answer :
B
Explanation :
The lac operon is a cluster of genes that involved in the metabolism of lactose in bacteria. The features associated with the lac operon are repressor, operator, promoter, and lactose. Master genes are not directly associated with the lac operon.
