Document Summary
Recombination nodule multiprotein complex, role is to maintain homolog alignment so that reciprocal genetic exchange can take place. 2 sister chromatids made a bivalent, those 2 get together to form a tetrad. Crossing over can take place between sister chromatids although they are identical: justified by j. h taylor"s experiment. Recombination nodule blobs of electron dense areas, multi-enzyme complex that cuts, etc. Band at bottom is cut and pasted 2 times after being flipped = inversion. Jumping early in kernel development = large purple sector, late in development = small sector: outer kernel = pericarp. Structures important for movement of transposons: direct and inverted repeats, transposon inserted = causes direct repeats how to get direct repeat. If transposon is by transposase cut so that it can be cut and put into another place (staggered cuts: ends of transposon are inverted repeats.
