Simply put, a genetic mutation comes from a change in the DNA; this change can result from an extrachromosomal element, an alteration of the inherited nucleotide...

Answer:
Antibiotics cannot be used for the treatment of viral infection because cellular architecture of both virus and bacteria are very much different with respect to each other.
Explanation:
Antibiotics target various physiological process of bacteria such as cell wall synthesis,assembly of ribosomal subunit,folic acid synthesis,cross linking of peptides to the peptidoglycan of the cell wall.
But if we study the viral cell we will found that virus neither contain cell wall nor ribosomes and viral metabolites are very simple in comparison to that of bacteria.That"s why antibiotic cannot be used for the treatment of viral infection.
Antibiotics wil unable to find any target in viral cell to exert its function.
The diagram is not found here, but the order of steps in the cellular division is interphase (G1, S and G2) >> mitosis >> cytokinesis. It is the cell cycle.
<h3>What is the cell cycle?</h3>
The cell cycle refers to the events that occur from a cell form until it divides to produce two daughter cells.
The cell cycle can be divided into interphase, mitosis and cytokinesis (i.e., division of the cell cytoplasm).
Interphase has there main steps, i.e., Growth 1 (G1) phase, Synthesis (S) phase, and Growth 2 (G2) phase.
In turn, mitosis can be divided into prophase, prometaphase, metaphase, anaphase and telophase.
