example, it is concluded that RNA is synthesized in both nucleus 

 and cytoplasm and that some movement of RNA or its immediate 

 precursors from nucleus to cytoplasm occurs. But a large gap

 morphological evidence; some of it eventually should turn out 

 to be significant. But it is decidedly premature to say that any of 

 it is more than suggestive.
