How is a nucleotide built up (draw structure) and which are the 5 nucleotides + what are they used for?

The five nucleotides are: Adenine, Guanine, Cytosine, Thymine and Uracil. They are the building blocks of DNA and RNA.

What are the 4 most common phospholipids?

Phosphatidylethanolamine, phosphatidylserine, phosphatidylcholine, sphingomyelin.

Which is the most common phospholipid in eukaryotes vs prokayotes?

In eukaryotes it is phosphatidylcholine, while in prokaryotes it is phosphatidylethanolamine.

What is the difference between the lipids in the membranes between eukaryotes and prokaryotes?

In prokaryotes (bacteria), there is usually only one kind of lipid in the membrane and no cholesterol.
