In immunofluorescence studies you always see the small G-protein Ras in a specific region of the cell and, given its protein sequence along with many other proteins localized to this area, you hypothesize that their C-terminal Cys-Ala-Ala-X (X can be any amino acid) motifs may be responsible for targeting these proteins to this subcellular region. To test this hypothesis, you genetically engineer the sequence encoding this motif onto a cDNA encoding green fluorescent protein. When immunofluorescence is used, where specifically would you expect to see GFP localized in the cell?

The first step in polar transport is auxin influx. According
to the model, auxin can enter plant cells from any direction by either of two
mechanisms:
a) Passive diffusion of the protonated (IAAH) form across
the phospholipid bilayer
b) Secondary active transport of the dissociated (IAA–) form
via a 2H+–IAA– symporter
c) Active diffusion of the protonated (IAAH) form across the
phospholipid bilayer
Find out the correct statements of about diffusion of IAA.
