The genetic material of prokaryotic cell:
| 1. | Non histonic double-stranded DNA |
| 2. | Histonic double-stranded DNA |
| 3. | Histone & DNA both are absent |
| 4. | Histone without DNA |
Chromosomes in a bacterial cell can be 1–3 in number and:
| 1. | Are always circular |
| 2. | Are always linear |
| 3. | Can be either circular or linear, but never both within the same cell |
| 4. | Can be circular as well as linear within the same cell |
