You observe a small, nonpolar molecule near a membrane. how would this molecule likely transport across the membrane? you observ
yaroslaw [1]
It will transported across plasma membrane by simple diffusion. simple diffusion refers to a process by which molecules will pass across plasma membrane without the aid of channels located on the surface of the membrane. since the molecule identified was polar once it enter in hydrophobic region of the membrane it will not stick since this region is non-polar and therefore it will move easily across that region.

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.
