Question: the atomic mass unit or dalton da is a small...

Question details

The atomic mass unit, or dalton (Da), is a small unit of mass used to express atomic and molecular masses. It is particularly useful for macromolecules such as DNA and proteins. 1. The polyprotein Gag of the HIV-1 virus has a mass of 55 kDa. What is its molar mass (g/mol of the protein)? About 2500 copies of Gag assemble to form the lattice of the HIV-1 virus. What is the molecular mass of the lattice? 2. A protein of molecular weight 55 kDa has a cellular concentration of 1 nM (one nanomolar- one nanomole per liter). What is the number density of this molecule (the number of molecules
