The nuclear membrane.
In eukaryotic cells, DNA is transcribed into mRNA within the nucleus. Once transcription is complete the mRNA must exit the nucleus to be translated into protein, which ocurrs in the cytoplasm. Thus, mRNA must pass through the nuclear membrane.
nuclear membrane
mRNA is produced in the cell's nucleus during transcription, where it is assembled using a DNA template. Once the mRNA has been created, it is then able to pass through the nuclear membrane and into the cell's cytoplasm for translation to occur and proteins to be produced.
What you are considering when you are referring to how easily materials can pass through a membrane is how permeable the cell wall or membrane is.
The reason why the cell membrane requires a fluid consistency is to allow certain molecules to pass through. Fluidity is also important for phagocytosis to take place.
A substance must pass through the cell membrane in order to enter or leave a cell. This process can occur through various methods such as simple diffusion, facilitated diffusion, active transport, or endocytosis/exocytosis. The cell membrane acts as a barrier that selectively allows certain substances to pass through while blocking others.

The Cell Membrane
Yes, charged molecules can pass through the membrane.
water and nutrients.
All particles trying to get into the cell must get through the cell membrane. The cell membrane is selectively permeable, which means that it can select what goes in and what goes out. The structure of a cell membrane is called a lipid bilayer, which is two layers of phospholipids.
intracellular fluid
The cytoplasm of a cell is surrounded by a cell membrane or plasma membrane. The membrane is said to be 'semi-permeable', in that it can either let a substance pass through freely, pass through to a limited extent or not pass through at all.the membrane is somewhat effective at letting fluids through
mRNA can leave the nucleus because it is a single-stranded molecule that is small enough to pass through the nuclear pores in the nuclear membrane. This allows it to carry genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm for protein synthesis.
Ions cannot pass through the cell membrane because the membrane is selectively permeable, meaning it only allows certain substances to pass through. Ions have an electric charge that makes it difficult for them to pass through the hydrophobic interior of the membrane.
The cellular transport and cellular communication factor that limit the cell size because all the materials that go in and out of a cell must pass through the plasma membrane.
