Question

You have discovered that the RNA transcribed from Gene X in maize is required for the regulation of Gene Y. The RNA of Gene X is not translated into proteins. However, in its absence, the levels of protein Y (product of Gene Y) are significantly increased. Propose one likely mechanism for how Gene X may be controlling the levels of Protein Y.

This is the current answer I have:

mRNA of Gene X in maize is a non-coding RNA

It is functional but it does not get translated into a protein

It binds to the complementary sequence that is present on Gene Y mRNA

Therefore, Gene Y mRNA undergoes cleavage or degradation

This results in the blocking of translation of Gene Y mRNA

Therefore, levels of protein Y are absent in presence of Gene X mRNA

In the absence of Gene X mRNA, Gene Y mRNA is not cleaved or degraded

As a result, Gene Y mRNA is translated and this results in significantly increased levels of Gene Y protein in the absence of Gene X mRNA.

Is this correct?

Explanation / Answer

In genetic regulation of a gene by mRNA to regulate the expression or protein translation is majorly contributed by long non-coding mRNAs. These reguate the gene expression at levels of translation or transcription. These molecules bind to the complementary sequnce of mRNA and block translation to proteins. Thus, genesare not transcribed or translated. When Gene X is not present, it does not bind to Gene Y mRNA , Gene Y is translated and thus, higher levels of proteins are present.

So, yes your answer is correct.
