| Popis: | The mRNA synthesized by sea urchin early blastulae consists of relatively few components that are small in size. In contrast, the nRNA is large and heterogeneous. When this “giant” nRNA is subjected to thermal denaturation in the presence of formaldehyde, no small components of the size of the predominant class of mRNAs (9 S) of these embryos can be detected. According to this criterion, “giant” heterogeneous, nRNA cannot be considered an aggregate of molecules of the size of mRNA. |
