Gene expression is defined as which of the following?
A
Genes are expressed because each cell contains a different set of genes
B
Choosing which genes are expression by regulating only transcription
C
Choosing which genes are expression because on only internal signals
D
Cells choosing to express some genes and not others at many steps in the DNA to protein pathway
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, usually a protein.
Recognize that gene expression is a multi-step process that includes transcription, RNA processing, translation, and post-translational modifications.
Acknowledge that cells regulate gene expression at various stages, allowing them to express some genes while repressing others, depending on internal and external signals.
Identify that gene expression is not limited to transcription regulation; it involves multiple regulatory mechanisms throughout the DNA to protein pathway.
Conclude that the correct understanding of gene expression involves the selective expression of genes at various steps in the pathway from DNA to protein, allowing cells to respond to their environment and maintain homeostasis.
