Write the command to read the first two lines of the pz_cDNA.fasta file. Look at these two lines. Notice the first one start with a ">" while the second line contains a sequence. Each sequence in the file has a first "descriptive" line that begins with ">" followed by numerous lines which contain the sequence. .. Read the contents of the file using UNIX. List all the ways you know to read a file. How many lines are in the file? . From the pz_cDNA.fasta file print only those lines that describe the sequences. (recall that description lines in a fasta format begin with ">") How many sequences are in this file? On each line that has a sequence on it, change all T to U and store in a new file called p2_CRNA.fasta. . First identify all the records that have the pattern with an "_" in the sequence ID - part of the description ( so it matches PZ21537_A but not PZ832049). 1. Then remove the underscore and anything that comes after it so that PZ21537_A becomes PZ21537
