Nucleotide composition and arrangement of soluble RNA in posterior silkgland

Abstract

• 1.

  1. The nucleotide composition and nucleotide arrangement of soluble RNA in the posterior silkgland have been compared for two kinds of silkworm, which produce two different kinds of fibroin which differ in their amino acid composition.

• 2.

  2. The s-RNA's from the two kinds of worm are similar to each other in their nucleotide composition and arrangement.

• 3.

  3. Some differences have been observed in the nucleotide arrangements when compared with yeast s-RNA. A few minor components including pseudo-uridylic acid are also detected in silkgland s-RNA.

• 4.

  4. The composition of the ribosomal RNA is similar in the two kinds of worm.
