The structure of plasma membrane makes it selectively permeable allowing it to regulate the passage of substances into and out of the cell. Small nonpolar molecules can easily across the phospholipid bilayer of plasma membrane because it is hydrophobic. Polar molecules and ion cannot easily across the hydrophobic portion of plasma membrane because it is hydrophilic. Polar molecules and ions usually across the plasma membrane with the help of transport proteins.
Answer:
Through nuclear pores.
Explanation:
The nucleus of a eukaryotic cell is double membrane-enclosed organelles which enclose the genetic material of the cell.
Although the nucleus contains the nuclear membrane but the molecules are exported and imported into the cells through small pores known as the nuclear pores.
The mRNA is synthesised through the process of the transcription is exported out of the nucleus through these nuclear pores.
Thus, the nuclear pore is correct.
