Q1. You are given the genomic sequences of two viruses (Ebola and SARS-COV2) in two files ebola.txt and sarscov2.txt, respectively. Using string processing in R, perform the following tasks. [30 points: 5+5+5+5+5+5] • First read the sequences of these viruses in two different R variables. • Replace each occurrence of 'T' by 'U' in both the sequences. Viruses are single- stranded RNA molecules where all nucleotide 'T' is replaced by 'U'. • Find the length of the sequence of the two viruses. The final few characters in a virus sequence have important role to play in the pathogenic properties of the virus. Display the last 20 characters in the sequences of the viruses. Do you notice any differences between them? Find out the fraction of times the four nucleotides A, U, G, and C occur in the virus sequence. The resulting data frame should look like this: # AUG C virus ## 10.3191961 0.2690299 0.1981326 0.2136414 ebola ## 20.2994348 0.3208374 0.1960673 0.1836605 sars-cov2 . Write R code to visualize the above results as a bar plot shown below:
