tmp$ cat dna.txt
aaaaaaaaaa aaaaaaaaaa
bbbbbbbbbb bbbbbbbbbb
cccccccccc cccccccccc

endtag

tmp$ ./reformat.sh
 aaaaaaaaaa bbbbbbbbbb cccccccccc 
 aaaaaaaaaa bbbbbbbbbb cccccccccc 


tmp$ cat reformat.sh
#!/bin/sh

FILE=dna.txt

cat $FILE | while read LINE ; do
   read FIRST SECOND <<EOL
$LINE
EOL
   
   if [ "$FIRST" = "endtag" ] ; then
      echo "$LINE1"
      echo "$LINE2"
   else
      LINE1="$LINE1 $FIRST"
      LINE2="$LINE2 $SECOND"
   fi

done


It's really important the "endtag" at the end.
Good luck.
