For the answer to the question above, <span>I assume you are referring to DNA replication which takes place in the synthesis (S) phase of the cell cycle shortly before G2. If that doesn't happen, the cell will not proceed to G2 and eventually mitosis, thus division will not complete. </span>The new cells would have an incorrect amount of chromosomes.
A classification system is a system with a distribution of classes created according to common relations.
The right answer is: The antibodies mistakenly identify the cells as foreign material.
The role of an antibody is to recognize a foreign antigen in order to neutralize it. They can achieve this thanks to the great specificity of their paratope, which recognizes only a very precise part of the antigen: the epitope. As soon as an antibody recognizes an epitope, the B lymphocyte that codes for that specific antibody multiplies and matures in order to synthesize the same antibodies, useful in large quantities.
The phenomenon described in the question is an autoimmunity mediated by autoantibodies.
An autoantibody is an antibody produced by the immune system and directed against one or more proteins of the individual himself
Many autoimmune diseases are due to the presence of these autoantibodies, but the presence of autoantibodies is not necessarily synonymous with such a disease.
Some scientists say that they could have a beneficial role in cleaning up cell debris resulting from a disease.
The way in which these autoantibodies are produced, their precise role, and the reason why they decrease in individuals with certain diseases, are all issues that remain unresolved.
Hi!
The cell would most likely be unable to synthesize proteins for both internal and for external use, and will consequently not be able to sustain itself.
Ribosomes play an essential role in the process of translation through which the code on an mRNA molecule is translated into a protein. Proteins have an indispensable role in intracellular chemical process, and are required by the cell for its repair.
Hope this helps!
I could be wrong but I believe the answer is True.
