Which of the following statements is/are CORRECT from the following?
I. The chromosome of the small monkey DNA virus SV40 is a circular, double-helical DNA molecule of 5000 bp.
II. The phage Lambda genome is a linear single-stranded molecule in the virion particle.
III. Circular DNA molecules purified from both bacteria and eukaryotes are usually negatively supercoiled, having values of sigma of approximately –0.06.
