* This is the phi6 genome:
[[file:phi6 RefWT_from Lele.txt]]
* CSV file
[[file:phi6 wt protein start stops.csv]]
This is a CSV file with three columns: protein name, start nucleotide, ending nucleotide
These numbers are inclusive. Everything else in the genome that’s not in at least one of those ranges (there’s one nucleotide overlaps
between some reading frames) isn’t protein-coding.
* Standard genetic code
[[file:Genetic-Code-Amino-Acid-Codon-Chart-sidebyside-03.png]]
The standard genetic code that you’ve used for some of my class projects applies, we will be using the single capital letter abbreviations for
amino acids. Because of this please use lowercase “a, c, g, t” for nucleotides. This is a chart that uses the DNA bases (no need to switch “u”
to “t” in your head) and has the single letter amino acids. The three stop codons (taa, tag, tga) should all code for the same thing — could be
“STOP” could be an asterisk… you can have some creative control here :-)
* Test
As a test that our coordinates are correct, can you spit out the protein sequence from each of those proteins? Each will start with a M (one with
a V, it’s an “alternate start codon) and should stop with a stop. Please send me that as a text file.
If that works I’ll get you sample input and output for what we need the program to actually do
have a nucleotide number and nucleotide inputted
print out reference sequence nt at that number, the nt number, the inputted nucleotide (Tab) the name of the protein involved OR
“noncoding” (Tab) Amino acid called by wild type sequence, the number in the protein that amino acid is, the amino acid called by the
inputted nucleotide being in the sequence.
Something like:
input 7500g
output:
a7500g P7 S34T
(sometimes the variant nucleotide will be in a protein-coding region but won’t change the called amino acid, this is normal and fine so we’ll
see, for example, “S34S”
Thanks!
