| | * The mRNA sequence will be transcribed from the transcription start site all the way to the end of the terminator. To simplify this solution, I created a command to perform the computation for me. In order to do this, I used the original command that I had used above. I knew I could delete everything before the transcription start site. If I placed a newline before the tss, I could remove the first line using the command "1D". However, this command could be further simplified. If I placed a newline before and after every tag, I could isolate the lines that contain nothing but tags, and remove them. Running the commands <code>sed "s/ //g" | sed -r "s/<|>/\n/g"</code> after the commands listed in the "terminator" part above, I was able to break the block of text into 29 lines, with the tag data to be removed on every other line starting at line 2. The data before the transcription start site was located on lines 1-10, and the data after the terminator was on line 29. Therefore, I could run the command <code>sed "1,10D;12D;14D;16D;18D;20D;22D;24D;26D;28,29D"</code> and delete every one of the unnecessary lines. Removing the newlines left me with a string of DNA that needed only the t's converted to u's. The final command and output is as follows: | | * The mRNA sequence will be transcribed from the transcription start site all the way to the end of the terminator.
