In most prokaryotes, how is chromosomal DNA primarily packaged within the cell?
A
As RNA–DNA hybrids packaged inside an icosahedral capsid until cell division
B
As a nucleoid: a highly supercoiled circular chromosome organized by nucleoid-associated proteins (e.g., HU, IHF) without a membrane-bound nucleus
C
As multiple chromosomes condensed by protamines into a tightly packed sperm-like chromatin structure
D
As linear chromosomes wrapped around histone octamers to form nucleosomes within a membrane-bound nucleus
