THE linear DNA of the human adenoviruses type 2 and type 5 (Ad2, Ad5) replicates in the nucleus of permissive cells by a mechanism different from that of chromosomal DNA or papovavirus DNA. Papovaviruses replicate bidirectionally, with both parental stra

Is DNA polymerase 1 used in the leading strand? If RNA polymerase is responsible for separating DNA strands during transcription, then what does Helicase do? Explain why DNA polymerase can continuously add fragments onto the leading strands 3'-5', but cannot do the same for ...
DNA polymerase III appears to be essential for normal DNA replication because semiconservative synthesis stops very quickly when strains (E mutants) temperature sensitive for DNA polymerase III are raised to the restrictive temperature. Two mutants deficient in DNA polymerase II have been isolated; but...
DNA DNA Enzymes DNA Polymerase DNA Primase DNA Replication DNA Synthesis siRNA Introduction In eukaryotes, DNA polymerases (Pols)3 α, δ, and ϵ jointly support DNA replication, and their overall roles in this process have been defined (1). The initiation of DNA replication is catalyzed by ...
What is the role of DNA polymerase III? How are the hydrogen bonds important in the replication of DNA? What is helicase? Describe its role in DNA replication. What role do single-strand binding proteins play in DNA replication? What is the function of the DNA polymerase? Is it for DNA ...
Here, we study σ-dependent synthesis of a transcript that is used to prime replication of the single-stranded genome of bacteriophage M13. We show that, in this system, σ plays no role in DNA recognition, which is accomplished solely through RNA polymerase core interaction with DNA downstream...

Repetitive DNA sequences playing critical roles in driving evolution, inducing variation, and regulating gene expression. In this review, we summarized the definition, arrangement, and structural characteristics of repeats. Besides, we introduced diverse biological functions of repeats and reviewed existing...
