what phase of transcription occurs when double stranded dna is separated?
dna replication
after escaping the promoter and shedding most of the transcription factors for initiation, the polymerase acquires new factors for the next phase of transcription: elongation. transcription elongation is a processive process. double stranded dna that enters from the front of the enzyme is unzipped to avail the template strand for rna synthesis. for every dna base pair separated by the advancing polymerase, one hybrid rna:dna base pair is immediately formed. dna strands and nascent rna chain exit from separate channels; the two dna strands reunite at the trailing end of the transcription bubble while the single strand rna emerges alone.
eukaryotic transcription
a group of double stranded dna viruses have been found in fish that appear to be related to the herpesviruses.









































another group of viruses that infect fish has been described.









































section::::pleolipoviruses.









































a group known as the pleolipoviruses, although having a similar genome organisation, differ in having either single or double stranded dna genomes. within the double stranded forms have runs of single stranded dna. these viruses have been placed in the family "pleolipoviridae". this family has been divided in three genera: alphapleolipovirus, betapleolipovirus and gammapleolipovirus.
