You find a specialized type of RNA in the nucleus but nowhere else in the cell, including the cytoplasm. What type of RNA is it?
- A. rRNA
- B. scRNA
- C. snRNA
- D. mRNA
Correct Answer: C. snRNA
Explanation
mRNA will be found in both the nucleus and in the cytoplasm because it is transcribed from DNA in the nucleus and then exported to the cytoplasm to go through translation. tRNA will be found in the cytoplasm because it is an integral part of translation in that it delivers amino acids to the ribosome. rRNA will also be found in the cytoplasm because it couples with ribosomal proteins to make up the ribosomes found in the cytoplasm. scRNA is also known as small cytoplasmic RNA and has a function that is still not very well known, but they are mostly only found in the cytoplasm. snRNA, or small nuclear RNA, are only found in the nucleus and are an integral part of splicing introns of RNA so it can go onto becoming mRNA.
