Suggest a means by which you could separate mrna from the other types of rna in a eukaryotic cell
jok3333 [9.3K]

A method by which you could separate mRNA from the other types of RNA in a eukaryotic cell is oligo (dT) chromatography.

<h3>What do you mean by mRNA?</h3>

mRNA may be defined as a molecule in cells that holds codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm.

The mRNA can be easily isolated from other types of RNA by the most reliable and convincing method of oligo (dT) chromatography which is the magnetic separation method that bounds oligo (dT) molecules on the surface of paramagnetic beads.

Therefore, a method by which you could separate mRNA from the other types of RNA in a eukaryotic cell is oligo (dT) chromatography.

We get day and night because the Earth spins (or rotates) on an imaginary line called its axis and different parts of the planet are facing towards the Sun or away from it. It takes 24 hours for the world to turn all the way around, and we call this a day.
