Copy numbers were estimated as follows: (a) When 10,000 clones, which represented about 3 × 104 kbp of rasbora genomic DNA, were screened with the Ras1 SINE, four clones, which represented about 1.2 kbp of Ras1 SINEs, were isolated by hybridization. (b) 5,000 clones, which represented about 1.5 × 104 kbp of lamprey genomic DNA, were screened with the Lam1 SINE, and 25 clones, which represented about 6.3 kbp of Lam1 SINEs, were isolated by hybridization. (c) 5,000 clones, which represented about 1.5 × 104 kbp of lungfish genomic DNA, were screened with the Lun1 SINE, 75 clones, which represented about 23 kbp of Lun1 SINEs, were isolated by hybridization. (d) The number of Ac1 SINEs in the medaka genome was estimated from the intensity of signals on a Southern blot (data not shown). (e) In fugu, about 3.5 kbp were identified as Ac1 SINEs in the 2 × 104 kbp of the fugu genome that have been sequenced to date (http://fugu.hgmp.mrc.ac.uk).
