Question
Which of the following could potentially affect the expression of multiple genes in a cell?
options:
All the answers are correct.
Blocking mRNA translation.
Expression of a transcription factor in which a conserved amino acid in the DNA-binding domain has been deleted.
A mutation in an activating region of a specific promoter.
Suppression of protein post-translational modifications.
All the answers are correct.
Blocking mRNA translation.
Expression of a transcription factor in which a conserved amino acid in the DNA-binding domain has been deleted.
A mutation in an activating region of a specific promoter.
Suppression of protein post-translational modifications.
Explanation / Answer
Answer: The expression of genes starts from the transcription, followed by translation and then by post-translational changes to acquire the target proteins in the cell. Every protein in the cell is destined to play a different role in the cell, therefore, exhibit different fate.
If the mRNA translation is blocked, no protein will form which may halt the expression of other proteins.
If the conserved amino acid in the DNA- binding domain has been deleted, it will lead to mutated gene product or no expression.
A mutation in an activating region of a specific promoter will lead to the mutation in protein, resulting affected gene expression.
Suppression of protein post-translational modification also affects the expression of multiple genes.
Therefore, the option all the answers are correct is true.
