thus , supercoiled hbv dna exists free in the nucleus of infected liver cells and cytoplasmic particles contain relaxed circular and linear hbv dna as well as a heterogeneous population of hbv dna and dna-rna hybrid molecules , and a dna polymerase reaction in the particles results in incorporation of dntp into dna strands of these molecules .
