Question

PLEASE READ THE QUESTION BEFORE ANSWERING.( MICROBIOLOGY) I posted this question but it was not answered correctly.

1.Outline three similarities and three differences of prokaryotic and eukaryotic cells.

2.Identify why the differences or similarities are relevant to understand. Consider implications such as laboratory identification, targeted drug therapy.

Answer 1

1.1 SIMILARITIES B/W PROKARYOTES AND EUKARYOTES

• DNA is the genetic material
• cytoplasm serve as the medium in which biochemical reactions take place
• ribosomes are present for carrying out translation.

1.2 DIFFERENCE B/W EUKARYOTES AND PROKARYOTES

PROKARYOTES

• size ranges from 1-10um
• cell wall is m,ade up of peptidoglycans
• dna is circular
• membrane bound nucleus and organelles are absent
• simple cell under microscope
• contain less stuff
• unicellular

EUKARYOTES

• Size ranges from 10-100um
• cell wall if present is made up of cellulose(chitin in fungi)
• dna is linear with circular histone proteins
• membrane bound nucleus and organelles are present
• more complex cell under microscope
• contain lot of stuff in the cell
• could be uni or multicellular

1.2 UNDER LAB IDENTIFICATION

under the microscope both the cell shows presence of cytoplasm bounded by plasma membrane.Both the cell show dna as a genetic material with the help of certain experiments.both the type of cell shows the presence of flagella though used for difference purpose.

there is a good difference b/w the size of the cell.under very high resolution we can difference b/w the shape of dna , eukaryotes are mostly multicellular and consist of well defined organelles making it a complex cell.

TARGET DRUG THERAPY

there is a well defined difference in antibiotic selectivity in procayotic and eukaryotic cell.but the similarities between the functional rRNA sites in both prokaryote and eukaryotes limits the therapautic potential between the two.Controlling of microbial pathogens in eukaryotes and bacterial infections shows similarities as both repicate very fast in their host cells.ekaryotic and bacterial cell show many common features with respect to their drug therapy response.in terms of their biochemistry, metabolism, gene composition and biology eukaryotic cell are more similar to their host than bacteria.
