If the concentration of actin monomers is greater than the critical concentration for both the T-form and D-form polymer, what would be the outcome?

#Unit 2. Cellular Organization
  1. The tips of the actin filament will remain in the T form & will shrink.
  2. Both ends of the filament will be in the D form and will shrink.
  3. The tips of the actin filament will remain in the T form & will grow.
  4. Both ends of the filament will be in the D form and will grow.

Restriction fragment length polymorphism denotes that a single restriction enzyme produces fragments of different lengths from the same stretch of genomic DNA of different strains of a species or from different related species. RFLPs are detected as follows:

i.  Large molecular weight genomic DNA is isolated from several strains or related species;

ii.  The fragments in these digests are separated through electrophoresis

iii.  These 'DNAs are then digested with a selected restriction enzyme

iv.  Exposed to a suitably radio-labelled appropriate DNA probe under conditions favouring DNA: DNA hybridization

v.  The resulting gel lanes are transferred and fixed to a suitable solid support and

vi.   The free probes are removed

vii.  The fragments to which the probe has hybridized are detected by filming them as distinct bands on a suitable photofilm through autoradiography.
