5. The chromosome is considered as a linin bag filled with 

 chromatin. Therefore, in the interkinetic nucleus the chromosomes 

 are contiguous and the chromatin of adjacent chromosomes is discrete, 



6. The chromosomes arise in the prophase by the chromosomal 

 vesicles losing the achromatic globules within them and con- 

 tracting to form the apparently homogeneous metaphase chromo- 

 somes.
