What Mechanism is Used by a Bacterial Cell to Fit

Question

What mechanism is used by a bacterial cell to fit its DNA into the nucleoid region?
A)the formation of loop domains
B)supercoiling by topoisomerases
C)tight wrapping around histones to form nucleosomes
D)the formation of loop domains and supercoiling by topoisomerases
E)the formation of loop domains,supercoiling by topoisomerases,and tight wrapping around histones to form nucleosomes

Accepted Answer

Bacterial cells use the mechanism of the formation of loop domains and supercoiling by topoisomerases to fit their DNA into the nucleoid region. This allows the DNA to be compacted without the need for histones, which are found in eukaryotic cells. Tight wrapping around histones to form nucleosomes is not a mechanism used by bacterial cells.
