Which of the following is an example of a non-coding RNA?

mRNA
tRNA
rRNA
miRNA

The correct answer is: miRNA

Non-coding RNA is RNA that does not code for a protein and instead has regulatory or structural functions in the cell. All of the options provided are types of RNA, but only miRNA is a type of non-coding RNA. mRNA, tRNA, and rRNA are all involved in the process of protein synthesis, while miRNA regulates gene expression. Therefore, miRNA is the only correct answer in this context.
