Some viruses also encode special DNA polymerases, such as Hepatitis B virus DNA polymerase.

Some viruses also encode special DNA polymerases, such as Hepatitis B virus DNA polymerase.

Some polymerases add over 50, 000 nucleotides to a growing DNA strand before dissociating from the template strand, giving a replication rate of up to 1, 000 nucleotides per second.

Some of these viruses require host cell polymerases to replicate their genome, while others, such as adenoviruses or herpes viruses, encode their own replication factors.

Some painters have less interest in the experience of the moment, with its attendant urgencies and ambiguities, than in looking beyond the flux of particular impressions to a higher, more serene level of truth.

Some of the earlier episodes have touches of the supernatural, as suited to the legendary background.

Some historians have found his point of view not to their taste, others have complained that he makes the Tory tradition appear `` contemptible rather than intelligible '', while a sympathetic critic has remarked that the `` intricate interplay of social dynamics and political activity of which, at times, politicians are the ignorant marionettes is not a field for the exercise of his talents ''.

Some of these thoughts -- not all of them -- have taken organized form in later years.

He said, `` Some have criticized your book as being neither literary criticism nor history.
