Can dna pass through nuclear pores
WebNov 5, 2024 · Is DNA allowed to pass through the nuclear pores? Conclusions. We have established that nuclear uptake of DNA can take place by linear passage through nuclear pores, and that this import depends on a biochemistry distinct from that governing active protein import. Does plant cells have nuclear pores? A nuclear pore is a part of a large complex of proteins, known as a nuclear pore complex that spans the nuclear envelope, which is the double membrane surrounding the eukaryotic cell nucleus. There are approximately 1,000 nuclear pore complexes (NPCs) in the nuclear envelope of a vertebrate cell, but this number varies depending on cell type and the stage in the life cycle. The hum…
