Since their genome is of the same molecular type (DNA) as their hosts genome, they can use the host cellular machinery for replication, transcription and translation. Since Arthur Kornberg was awarded the Nobel Prize in 1959 for determining the roles of DNA polymerases during DNA replication, it has been widely accepted that the DNA polymerases involved in this process require a single-stranded template to construct a new DNA strand. In the proposed butterfly model for eukaryotic replication, the molecules that advance the two growing forks (see Box 1) that issue from an origin of replication are organized as a double replisome that is fixed to an element of the nuclear skeleton.Thus, the two growing forks remain bound to the double replisome throughout the duplication of the replicon. Many of them are also animated. If so, share your PPT presentation slides online with PowerShow.com. Thus, the ends are protected.
