Table 2.

Frequency of the TTT and TAC regions in the chaetognath ribosomal protein cDNAs with complete 5'-ends

Ribosomal subunit	TTT putative binding site (5'-TAATTGAGTAGTTT-3')		TAC putative binding site (5'-TATTAAGTACTAC-3')
	% of clones bearing this sequence	% of clones bearing a highly homologous sequence	% of clones bearing this sequence	% of clones bearing a highly homologous sequence
SSU RP genes	63.7	10.8	21.8	3.7
LSU RP genes	70.3	4.5	19.8	5.4

The percentage of identity between consensus sequences and highly homologous sequences is always ≥ 69%.
