What would happen if M RNA were radio actively labeled instead of polypeptides is that instead of one seeing the DNA passing through all the molecular factories you will instead see just messenger RNA taking code and delivering it to Ribosome. This is mainly found in cytoplasm and Endoplasmic recticulums.
A cell membrane has consists of phospholipids. They are lipids with a phosphate group such as (PO3/4). They are hydrophilic meaning that they allow water to pass through proteins well some at least- but it might be needed to move molecules throughnthe membrane as well. But basically it's just a composed bilayer of phospholipids with hydrophobic acid tails so that they could all meet with one another. The form complexes into function to describe or to identify the cells to anothers cells.
Hope this helps.
