Given the following list of antibiotics and their targets, explain how each stops bacteria without harming human cells. Base you
r analyses on the differences between eukaryotic and prokaryotic cells. Considering the targets of these antibiotics, explain why antibiotics in general would not be useful for treating a viral infection. Antibiotic
Target
Penicillin
Blocks cell wall synthesis
Tetracycline
Blocks protein synthesis by binding to the 30S Unit of the ribosome
Chloramphenicol
Blocks protein synthesis by binding to the 50S Unit of the ribosome
Sulfonamides
Inhibit folic acid synthesis
Vancomycin
Blocks cross-linking of the peptidoglycan in the cell wall
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.
Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.
Such direct observational evidence is limited, however, and clouds remain the biggest source of uncertainty--apart from human choices to control greenhouse gases—in predicting how much the climate will change
