Question

Most gene regulation happens at which step along the way.

  1. Translation
  2. Transcription
  3. Signal transduction
  4. DNA replication

hintHint:

Mostly gene regulation occurs when information in a gene's DNA is passed to mRNA which is called transcription.

The correct answer is: Transcription


    • Gene regulation can occur at any point during gene expression, but most commonly occurs at the level of transcription (when the information in a gene’s DNA is passed to mRNA).
    • Signals from the environment or from other cells activate proteins called transcription factors. These proteins bind to regulatory regions of a gene and increase or decrease the level of transcription. By controlling the level of transcription, this process can determine when and how much protein product is made by a gene.
