  • a Repeat positions are based on nucleotide sequence information described in reference55. Nucleotide repeats consisting of monomers [poly(A), poly(C), poly(G), or poly(T) tracts] were not searched for; 2-, 4-, 7-, and 8-unit repeats were not encountered. Repeats were identified by a computer program written by Stewart Scherer, University of California Los Angeles.

  • b The two sequence motifs were found to be adjacent; both motifs occurred five times and were exactly neighboring.
