Which of the following statements about gene expression is true?
A
Gene expression is regulated only at the transcriptional level.
B
Gene expression can be regulated at multiple levels, including transcription, translation, and post-translation.
C
All genes in a cell are expressed at the same level at all times.
D
Gene expression is not influenced by environmental factors.
Verified step by step guidance1
Understand that gene expression refers to the process by which information from a gene is used to synthesize a functional gene product, often a protein.
Recognize that gene expression can be regulated at multiple stages: transcription, RNA processing, translation, and post-translation.
Consider transcriptional regulation, where the synthesis of RNA from DNA is controlled by factors such as transcription factors and enhancers.
Acknowledge that translation regulation involves controlling the process by which ribosomes synthesize proteins from mRNA.
Realize that post-translational regulation includes modifications to proteins after they are synthesized, affecting their function and activity.
