A scientist is interested in producing flowers with a darker red color. To do this, the scientist alters the promoter of the gene to make it more active. This results in increased transcription and increased red pigments. The scientist then alters the promoter to make it even more active. This results in white flowers with no red pigment. Genetic research showed an increase in the siRNA in the cell. What did the siRNA do to the mRNA?

The siRNA caused the mRNA to be broken down.

The siRNA caused alternative splicing of the mRNA.

The siRNA caused increased methylation of the mRNA.

The siRNA caused the ribosome to no longer recognize this mRNA.

The correct answer is: The siRNA caused the mRNA to be broken down.
