Yeah, you didn't specify what you wanted it to do. This one allows you to specify with the default_char variable what unspecified chars will be mapped to (presently it's at a space, but you could replace with an empty string or some other default char/string easily).

class String
def dna_conv
 default_char = " "
 dict = {"A" => "ABCDEF", "B" => "GHIJKL", "C" => "MNOPQR", "D" => "STUVWXYZ"}
 self.upcase.each_char.map{|input_char| found_pair = dict.detect{|key, value| value.include?(input_char)}; (found_pair && found_pair.first) || default_char}.join
end
end

puts "DNAS: Sequencing Open... Input? "
while (word=$stdin.gets.chomp).size>1
 puts word.dna_conv
 puts
 puts "DNAS: Additional Input? "
end
