Measurement of translational accuracy in vivo: missense reporting using inactive enzyme mutants.

abstract：:The nucleotide sequence of the gene encoding chicken ribosomal protein L7a was determined. The gene contains eight exons and seven introns, which spread over 3613 nucleotides. The transcription initiation sites were located on four consecutive nucleotides GCCC, which are at the 5' terminus of a short polypyrimidine tr...
