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 |
