When yоu аre finished with this prоgrаm аnd ready tо move on to the next, please copy and paste “Question 1 of the Proctored Final Exam is complete and ready for grading.” in the text box for this question. Program 1: Identify DNA Transitions and Transversions When point mutations occur in DNA, researchers often categorize them based on whether the mutations are transitions or transversions. A transition occurs when one purine nucleotide (A and G) is mutated to another purine nucleotide or one pyrimidine nucleotide (T and C) is mutated to another pyrimidine nucleotide. A transversion occurs when a purine nucleotide is mutated to a pyrimidine, or pyrimidine to purine. This exercise will focus on determining the total number of passing mutations and the percentage of transitions and transversions. There are four different types of transitions: A mutated to G (i.e. this would be an A in the “Ref” column and G in the “Var” column) G mutated to A T mutated to C C mutated to T There are eight different types of transversions: A mutated to C (i.e. this would be an A in the “REF” column and C in the “VAR” column) A mutated to T G mutated to C G mutated to T C mutated to A C mutated to G T mutated to A T mutated to G Write a Python program that uses sys.argv to accept one command line argument. This argument will be the name of a VCF file. Consider only variants with a FILTER value of PASS. Your script should count the total number of variants with PASS in the FILTER column, and calculate the percentage of DNA transitions and transversions within the specified VCF file (consider only variants that pass quality controls). Calculate the percentage as the number of transitions (or transversions) divided by the total number of variants that passed the quality filter. Then multiply this number by 100. Finally, do not round this number. For example, if the server were to run your code on VCF_file1.vcf (see above), it would execute the following command: python studentcode.py VCF_file1.vcf Expected output printed to the screen (case should match exactly, there is one space between words, numbers, and percentages, and the percentages are not rounded…the percentages might have many numbers after the decimal, but in this case only have one. Do not round percentages.): 5 variants40.0% transitions60.0% transversions
When yоu аre finished with this prоgrаm, pleаse cоpy and paste “Extra Credit Question 3 of the Proctored Final Exam is complete and ready for grading.” in the text box for this question. Program 3: Annotate Variants (5 Points Extra Credit Possible) After identifying shared variants, in order to determine if one of them might be causing the phenotype, it’s necessary to figure out which gene harbors each of the shared mutations. Your task is to take a file formatted the same as your output in Question 2 (list of shared variants) and determine which gene each of the mutations is from. You will not be given the exact file you created in Question 2, just a file that’s formatted the same: four columns, where column 1 is the chromosome, column 2 is the chromosome position, column 3 is the reference allele, and column 4 is the variant, or mutated, allele. You will also be provided with a gene annotations file, which has four columns: chromosome, start position (inclusive), stop position (inclusive), and gene name. Your task is to determine which gene each variant is located in and create a new file exactly the same as the shared variants file except it will have another column with gene name, or “no gene” if the mutation isn’t located in a known gene. To be located in a gene, a mutation should be located on the same chromosome and in a position within the range defined by the genes file. Your program should accept three files from the command line (in the following order): shared variants file, output file where you’ll write your new file, and the genes file. It is possible that more than one mutation will be in the same gene, some mutations will not be located in a gene, and not all genes from the gene annotations file will be used. Following is an example, assuming I have the two following files: shared_variants.txt: chr1 3675 A Ghr1 3789 T Gchr11 55 T C gene_annotations.txt: chr1 3700 6000 GeneAchr2 3300 10000 GeneBchr2 11000 12000 GeneCchr11 55 4500 GeneD Example #1 If I execute the following command: python studentcode.py shared_variants.txt gene_annotations.txt annotated.txt. Your program should create the following file, annotated.txt: annotated.txt (all uppercase and tab-delimited): CHR1 3675 A G NO GENE CHR1 3789 T G GENEA CHR11 55 T C GENED
