*The transcription start site, according to the week 4 assignment, was the 12th letter after the minus 10 box. As a result, I knew that I would have to start my search at the -10 box tag. If the newline that created a line after the -35 box was still there, the second line could be searched for the instance of the characters "> ". This would indicate the last character of the -10 box tag. Since the code of the -10 box is 6 nucleotides, I know that the character 6 nucleotides after the end of the tag is the transcription start site. I could separate out this site with a newline, then surround the first character of this new line with the tag. At the end, both newlines could be removed using the same command as before. To make searching the 5 nucleotides after easier, I used the parameter -r into sed to allow me to input a repetitive pattern. The command is as follows: | *The transcription start site, according to the week 4 assignment, was the 12th letter after the minus 10 box.
