Contents
- 1 Write a sequence of piped text processing commands that, when given a nucleotide sequence, returns its complementary strand.
- 2 Write 6 sets of text processing commands that, when given a nucleotide sequence, returns the resulting amino acid sequence, one for each possible reading frame for the nucleotide sequence.
Write a sequence of piped text processing commands that, when given a nucleotide sequence, returns its complementary strand.
Sequence used: 5'-gcattaggcaac-3'
- Used sed "y/atgc/tacg/" to perform complimentary base pairing
Resulting sequence: 3'-cgtaatccgttg-5'
Write 6 sets of text processing commands that, when given a nucleotide sequence, returns the resulting amino acid sequence, one for each possible reading frame for the nucleotide sequence.
Sequence used: 5'-gcattaggcaac-3'
- Used sed "y/t/u/" to change all t's to u's
Resulting sequence: 5'-gcauuaggcaac-3'
+1 Reading Frame: 5'-gca uua ggc aac-3'
- Used "sed "s/gca/A/g" to replace the first codon with A
Resulting sequence: 5'-AuuagAac-3'
- This is not the desired result
- Used "sed "s/^gca/A/g" to replace only the first codon with A
Resulting sequence: 5'-Auuaggcaac-3'
- Used "sed "s/uua/L/g" then sed "s/ggc/G/g" then sed "s/aac/N/g" to get the final result
+1 Reading Frame Amino Acids: ALGN
+2 Reading Frame: 5'-g cau uag gca ac-3'
- Used sed "s/^g/ /g" then sed "s/cau/H/g" then "s/uaggcaac/ stop/g"
Resulting sequence: H stop
