b Nuclei from different embryonic stages are allowed to synthesise RNA with tritiated ATP or GTP 

 under conditions which will show if initiation sites for transcription become more or less A-T rich 

 and if HI histone covers more A-T rich and repetitive initiation sites for transcription during 

 development. (Anura) , ^
