Can dna pass through nuclear pores
WebDNA is a large and complex molecule that contains the genetic information necessary for the proper functioning and development of an organism. It is too large to pass through the nuclear pores, which are the tiny openings in the nuclear envelope that allow molecules to move in and out of the nucleus.

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…
