title: The synthesis of RNA and silk protein in Galleria mellonella silk glands.
abstract: The silk protein synthesis in silk glands of Galleria mellonella is preceded by the increase of total RNA content. The levels of the main RNA classes: 28S and 18S rRNA, tRNA as well as poly(A) + RNA change proportionally to the total RNA pool of glands. The fibroin-like silk protein of molecular weight of about 240 000 is characterized by the high content of four amino acids: glycine, alanine, serine and leucine, which account for more than 70% of amino acid residues. This fibroin-like protein is present in the posterior, middle and anterior parts of silk gland of the last instar larvae.
