Question

multiple choice 10 points
which of the following statements about gene regulation in eukaryotes is true?
transcription factors are unnecessary for gene regulation
eukaryotic cells use operons like prokaryotes
all genes in eukaryotic cells are always active
gene expression is mainly regulated at the transcriptional level

Explanation:

• Transcription factors are necessary for gene regulation in eukaryotes as they help in the process of transcription initiation.
• Eukaryotic cells do not use operons like prokaryotes. Operons are a characteristic of prokaryotic gene regulation.
• Not all genes in eukaryotic cells are always active; gene expression is regulated.
• Gene expression in eukaryotes is regulated at multiple levels (transcriptional, post - transcriptional, translational, post - translational), not mainly just at the transcriptional level.

Answer:

Gene expression is mainly regulated at the transcriptional level
