a precursor of 5s ribosomal rna from bacillus subtilis ( p5a rrna , 179 nucleotides in length ) is cleaved by rnase m5 , a specific maturation endonuclease which releases the mature 5s rrna ( m5 , 116 nucleotides ) and precursor fragments derived from the 5 ' ( 21 nucleotides ) and 3 ' ( 42 nucleotides ) termini of p5a rrna .
