Question

Which of the following would be the best way to determine whether a cell belonged with Archaea or Bacteria?

Check to see if it can form a capsid around itself since only Bacteria can do that.

Test to see if it can survive in harsh environments since only Archaea survive these.

Test for the presence of a special form of RNA polymerase because only Bacteria has this.

Answer 6

\(\sf Archaea\)
Cell membrane contains ether linkages
cell wall lacks peptidoglycan
genes and enzymes behave more like Eukaryotes
have three RNA polymerases like eukaryotes and extremophiles

\(\sf Bacteria\)
Cell membrane contains ester bonds
cell wall made of peptidoglycan
have only one RNA polymerase
react to antibiotics in a different way than archea do.

Answer 7

Ok so would it be Test for the presence of a special form of RNA polymerase because only Bacteria has this.
