What else can I help you with?
What packs DNA tightly that large amounts fit inside a cell?
proteins
What role do proteins play in enabling the enormous amounts of DNA in the eukaryote cell to fit into the nucleus and what are the proteins called?
DNA that is not being "used" by the cell is wrapped up around proteins called histones.

How do large molecules get into the cell if they cannot fit via diffusion?
Through specialized carrier proteins in the cell membrane.
What packs DNA so tightly that large amount fit inside a cell?
proteins
How are proteins and lipids secreted out of the cell?
through active transport, as transport proteins are needed to fit them through the phospholipid bilayer. this requires energy, as the proteins are doing a lot of work to move the large molecules.
Are proteins assembled in the cell?
Ribosomes are the cell organelles that assemble proteins. They function as factories to produce usable proteins for a cell.
What kinds of proteins can be found in cell membranes?
There are two kinds of proteins in a cell membrane: peripheral PROTEINS OR trans membrane proteins. Cell membranes are able to perform various functions only because of different membrane protein functions. Most of the membrane proteins have alpha helix structure.
How does a eukaryotic cell fit its entire DNA into the nucleus?
It wraps the DNA around proteins, and then coils further forming a compact fiber.
Proteins do not pass through cell membranes because?
Proteins do not pass through cell membranes freely because they are large molecules that cannot easily fit through the membrane's lipid bilayer. Instead, proteins are typically transported into or out of cells through specific channels or transport proteins in a process called facilitated diffusion or active transport.
What are the proteins that control reactions in a cell?
The proteins that control reaction in a cell are enzymes.
Where in the cell are ribosomal proteins synthesized?
Ribosomal proteins are synthesized in the cytoplasm of the cell.
