title: [Comparative study of nuclear RNA and polysomal mRNA in sunflower seedlings].
abstract: A comparative study of nRNA and polysomal mRNA complexity in the sunflower seedlings by molecular DNA:RNA hybridization method was carried out. It is established that nRNA complexity 4 times exceeds that of mRNA and is equal to 4.85.10(8) bp. Thus the nuclear RNA is expressed from at least 50.47% of single-copy DNA or 10.40% of genome. This data allow the presence of regulation of sunflower genome expression on the posttranscriptional level to be assumed.
