Product Description: General inspection of a role performed in the cell by RNAs allows us to distinguish three major groups of transcripts: I. protein-coding mRNAs, II. non-coding housekeeping and III. regulatory RNAs. The housekeeping RNAs include RNA classes that are generally, constitutively expressed and whose presence is required for normal function and viability of the cells...read more

This book focuses on the RNA components of the ribosome and on group I introns emphasizing intrinsic properties of large RNAs common to both systems, splicing and translation. In particular, it demonstrates the fascinating versatility of genetic systems. (view table of contents)

Product Description: Biologists have long been puzzled by the peculiar arrangement of genes on the strands of DNA. Genes are interrupted by non-coding regions--intervening sequences or introns--that function in some developmental systems and probably were involved in the evolution of the earliest genes...read more
