The linear mass density can then be understood as the derivative of the mass function with respect to the one dimension of the rod (the position along its length =) The SI unit of linear mass density is the kilogram per meter (kg/m). Linear density of fibers and yarns can be measured by many methods.
An Arabidopsis thaliana chlorophyll(ide) a oxygenase gene (cao), which is responsible for chlorophyll b synthesis from chlorophyll a, was introduced and expressed in a photosystem I-less strain of the cyanobacterium Synechocystis sp.
This band has been identified as the light-harvesting chlorophyll-protein complex of photosystem II (33). This band is entirely absent in the mutant chloroplast membrane. Staining makes visible the full complement of membrane proteins. As can be seen in Fig. 3, the protein band corresponding to the light-harvesting chlorophyll-protein complex of photosystem II is completely missing, indicating that the loss of this band in the unstained gel was due to a complete absence of protein at this point in the gel, not just to a loss of pigment from the protein moiety of the
