A protein has a molecular mass of 400 kda when measured by gel filtration. When subjected to gel electrophoresis in the presence of sodium dodecyl sulfate (sds), the protein gives three bands with molecular masses of 180, 160, and 60 kda. When electrophoresis is carried out in the presence of sds and dithiothreitol (dtt), three bands are again formed, this time with molecular masses of 160, 90, and 60 kda. Required:
Determine the subunit composition of the protein.

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
