Syllabus Zoom Background Calendar EA DNA is made up of sequences of nucleotides. There are four nucleotides: Adenine, Cytosine, Guanine, and Thymine, represented by the letters A, C, G, and T. Inbox Every set of three nucleotides produces one of twenty amino acids. For example, Cytosine, Thymine, and Guanine (CTG) produce Leucine. Note that there are 64 combinations of three nucleotides, and only twenty amino acids, so that means that a single amino acid can be produced in many different ways. [ The following tables, taken from the Biolnformatics tutorial e are Copyright 1999 by Boris Steipe, University of Munich. The table at the left shows the names of the amino acids and their abbreviations. The table at the right shows the abbreviations of the amino acids and the nucleotide sequences which produce them.

Dashboard The program will continue to accept input until the user just presses ENTER without entering any DNA codes. Courses Calendar Here is a sample run of the program. Note that some sequences, such as TAG, do not produce an amino acid. They are listed as *** for their three-letter abbreviation. Do not presume that there will never be more than 4 sequences. Somebody could enter a string with 40 three-letter sequences, or 50, or 80, and your program would have to process that string correctly.

Courses Enter a nucleotide sequence, or just press ENTER to quit: Calendar Breaking a String into Triples BL Inbox This takes a bit of doing. I suggest you do this: Write a function named clean_sequence() takes a string as its single parameter. It will use a for loop to go through the string one character at a time; if the letter is alphabetic, convert it to upper case and add it on to the end of a result string. The function returns the result string. For example, clean_sequence('aaa, TCG, gaa') will return 'AAATCGGAA' Use a while loop that goes through the cleaned sequence one triple at a time and processes it. [ Program Requirements You must use at least one dictionary to implement this program. This file has the preceding tables without all the punctuation.
