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.

What do dna microarray assays allow scientists to study regarding gene expression?
Allisa [31]

DNA microarray assays allow scientists to identify networks of gene expression across an entire genome.

The microarray is scanned to determine the expression of each gene printed on the slide after hybridization. The associated spot on the microarray turns red if a particular gene's expression is higher in the experimental sample than in the reference sample.

The DNA microarray is a technology that is used to identify whether a specific person's DNA has mutations in genes like BRCA1 and BRCA2. The chip is made up of a tiny glass plate that is enclosed in plastic. A few businesses use techniques resembling those employed to create computer microchips to produce microarrays.
