I believe it is the Endoplasmic Reticulum (ER).
<span>For the answer to the question above, the mRNA stands for messenger RNA. The job of the messenger RNA is to copy the code from the DNA and go through a ribosome so a protein can be created.
rRNA stands or ribosomal RNA. It is essentially the ribosome and is comprised of the large and small subunit. The rRNA allows the mRNA to go through rRNA in order to create the amino acid chain.
tRNA stands for transfer RNA. tRNA brings amino acids to the coordinating codon on the mRNA and matches it to the correct codon.

Answer: B
Explanation:
The T helper cell needs to acttivate the T cyctotoxic cell in order for the Tc cell to go do its work.
Once the TC cell is active it interacts with MHC-1 proteins on the surface of the infected host cell, this allows the Tc cell to recignise the host cell and begin secreting cytotoxins (perforins and granzymes) in order to degrade the infected cell and cause apoptosis (controlled cell death)
