Researchers often want to isolate a certain type of RNA. For some RNA species, this can be accomplished via affinity chromatography, using beads coated with chains of poly-deoxythymidine (poly-dT). The desired RNA will stick to the beads while unwanted RNAs will flow through the column. The retained RNA can then be eluted.
What RNA species can be purified using this method?
A. bacterial mRNA
B. bacterial rRNA
C. eukaryotic rRNA
D. eukaryotic mRNA


Answer :

Eukaryotic mRNA species can be purified using this method.

Define the term Eukaryotic mRNA?

Eukaryotic mRNA is the type of mRNA found in eukaryotic cells, which are cells that contain a nucleus and membrane-bound organelles. Eukaryotic mRNA is transcribed from DNA in the nucleus and then transported to the cytoplasm where it is translated into proteins.

mRNAs in eukaryotes (but not prokaryotes) undergo many modifications, including a 5' methylguanosine cap and a 3' poly-A tail. These changes increase mRNA stability and enhance nuclear export. The poly-A tail allows researchers to isolate eukaryotic mRNAs from noncoding RNAs, which lack this characteristic.

Therefore, the correct option is Option D.
