Understanding DNA transcription and translation

Part 1. A DNA string is called an open reading frame (ORF) if it begins with ATG, ends with TGA, TAG, or TAA, and has a length that is a multiple of 3. ORFs are interesting because they can encode proteins.Write a function called orf_advisor(dna) that takes a string called dna (you can make up your own DNA string or copy one from Genbank) as input and works as follows:

The function orf_advisor(dna) returns the string This is an ORF. if the input string satises all three of the conditions required of ORFs.

Otherwise, if the rst three symbols are not ATG , the function returns the string The rst three bases are not ATG..

Otherwise, if the string does not end with TGA, TAG, or TAA, the function returns the string The last three bases are not a stop codon..

Otherwise, the function returns the string The string is not of the correct length.

Part 2. Write a function called codon_nder(mrna) where the input is expected to be a string named mrna representing the mRNA sequence UGUAUAAGGCCGAGG (remember, U replaces T in RNA). Your function should:

Oops- it turns out that your mRNA is in the 3 to 5 direction. Using string splicing (Zybooks chapter 7.1), your function should reverse the sequence so that its in the correct 5 to 3 direction. Hint: my_str[::-1] will do this.

Now that your mRNA sequence is in the correct orientation, your function should create a list (Zybooks 3.2) that contains each codon as an element in the order that it appears in the mRNA sequence.

Change the rst codon in the list to a start codon (AUG) and append the list with a stop codon (UAA, UAG, or UGA) at the end.

Use the codon translation and amino acid abbreviations tables (in lecture slides or Google) to nd the one letter code for each aminoacid that corresponds to each codon in your list. Include the start codon, which encodes an amino acid, but do not include the stop codon. Print The codons[insert your list] make a protein that is [insert protein sequence here]" so that the italicized text is replaced with the appropriate answers.

Return the list.

Add the answers you got from running your program to the top of the program as comments.
