Histogram of the initial positions of the palindromes scoring above threshold with respect to the stop codons. X = 0 is the position of the downstream stop codon of each Mimivirus gene. Palindrome positions refer to their 5′ extremities. A bin width of 10 nt was used. The presence of the palindromes strongly correlates with the beginning of the 3′-UTR, just after the stop codon. Forty palindromes overlap the stop codon, leading to extremely short 3′-UTRs (Table 1).
