Answer:

c)cytotoxic T cell is the correct answer.

Explanation:

On the surface of the Cytotoxic T cell, TCR's receptors and a cluster of differentiation (CD8) receptors are present.

The cells infected by a virus produce viral proteins and these viral protein are present on their membrane

Cytotoxic T cells kill the virus-infected cell when their receptors TCR's match with the viral antigen and as they recognize the cell infected with the virus they produce cytokines that eliminate the infection.

Thus cytotoxic T cell recognizes and destroys cells infected by a virus.

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.
