During initiation, the DNA is made accessible to the proteins and … Webb13 mars 2024 · DNA replication begins at a specific spot on the DNA molecule called the origin of replication. At the origin, enzymes unwind the double helix making its components accessible for replication. Each strand of the helix then separates from the other, exposing the now unpaired bases to serve as templates for new strands.

How does DNA replication initiate in animal cells?

WebbBACKGROUND INFORMATION: The interferon (IFN)-inducible protein TRIM22 (Staf50) is a member of the tripartite motif protein family and has been suggested a role in the regulation of viral replication as well as of protein ubiquitylation. In addition, we have previously shown that TRIM22 is a direct target gene for the tumour suppressor p53.
