A model for gene expression and regulation is shown here. Not all genes are expressed at all time, and a study of the proteins within a cell indicates that not all of the gene products are present within a cell. Analyze the model and evaluate which statement(s) below
are correct based on the gene expression. Select ALL that apply.
A)
Inactive DNA prevents the gene expression at the earliest stage.
B)
Removal of the mRNA before it is translated can regulate the gene
expression.
9
Regulation of the mRNA is the most efficient mechanism for reducing
gene expression
D)
DNA, once transcribed, will produce multiple protein products with very
little regulation in the process.
E)
The targeted destruction of the protein can reduce the overall expression
of the gene at a later stage in the process.
