B)processing-level controls
C)translational-level controls
D)replication-level controls
E)denaturation-level controls

Question

Quizplus · Accepted Answer

Transcriptional-level controls determine whether a gene is transcribed into mRNA, and how often it is transcribed. These controls occur at the level of DNA, and can involve factors such as transcription factors, chromatin structure, and DNA methylation. Processing-level controls and translational-level controls occur after mRNA is produced, and deal with processes like splicing, mRNA stability, and translation initiation. Replication-level controls are unrelated to gene expression, and denaturation-level controls are not a recognized level of gene regulation.
