Gene regulation in eukaryotes only occurs during the transcription stage of gene expression.
A
True
B
False
Verified step by step guidance1
Understand the concept of gene regulation: Gene regulation refers to the processes that control the expression of genes, ensuring that the correct genes are expressed at the right times and in the right amounts.
Recognize the stages of gene expression: Gene expression involves multiple stages, including transcription, RNA processing, translation, and post-translational modifications.
Identify where gene regulation can occur: In eukaryotes, gene regulation can occur at various stages, not just during transcription. It can also occur during RNA processing, translation, and through post-translational modifications.
Consider examples of regulation beyond transcription: For instance, alternative splicing during RNA processing can regulate gene expression by producing different mRNA variants from the same gene.
Conclude that gene regulation in eukaryotes is a multi-stage process: Therefore, the statement that gene regulation only occurs during transcription is false, as regulation can occur at multiple stages of gene expression.
