Thanks robert here are the results ran 100000 times for each approach

require 'benchmark'

iterations = 100000
Benchmark.bm do |bm|

bm.report("Brian:") do

iterations.times do
expand_seq "t[ac][tc]aaattaag[ga]gaag[ac]ttggtgga" do |seq|
# puts seq
end
end
end

bm.report("Jesus:") do
iterations.times do
/t[ac][tc]aaattaag[ga]gaag[ac]ttggtgga/.generate
end
end
end

user system total real
Brian: 36.500000 2.080000 38.580000 ( 38.738666)
Jesus: 217.180000 30.710000 247.890000 (248.848401)

It shows that a specialized solution could be more streamlined .
Anyway, my solution was never optimized for performance. Could be an
interesting project...
