Gene expression is often assayed by measuring the level of mRNA produced from a gene. The level of the control of gene expression that can by analyzed by this type of assay is (B) transcriptional control.
Gene expression is the process of making RNA and proteins from the gene. Therefore, gene expression is measured at two levels: at the transcription level and at the translation level.
Transcriptional control is the prevention of synthesis of m-RNA from the gene. It can take place at any stage of the transcription, from initiation to termination. Maximum of the control of gene expression occurs at transcriptional level.
