On the basis of the hybridization data we calculated 2,880 ribosomal genes per haploid genome. Poly(A)mRNAs are only coded for by unique DNA sequences. Preliminary r

The size distribution and molecular weights were determined by electrophoresis on polyacrylamide gels in formamide. The average molecular weight of

It is concluded that transcription activity depends on the proportion of decondensed chromatin, and that both may be controlled by differential DNA replication during early development of the eye.
