ATG B] Question No.3: In Python interactive mode or PyCharm IDE, write a function named check_start_coden that will allow a user to enter a DNA sequence from the keyboard using input)function. Make sure to give the user a prompt Enter your sequence" to know what is going on. Then, it will say "Your sequence starts with ATG" if the sequence starts with ATG (that is a start codon). Otherwise, it will say "Your sequence does not start with ATG". This method do not take any argument or parameter, and it will not return any object out of this function. After defining this function, you need to call it to make sure it works. Show your command to call your function. functiun >>> def check start codon): seq-input('Enter your sequence:') if seq.startswith("ATG"): I. t. t. print ("Your sequence starts with ATG") else: print("Your sequence does not start with "ATG") File "", line 6 print ("Your sequence does not start with "ATG") SyntaxError: invalid syntax >>> lets.check start_codon() Traceback (most recent call last): File "", line 1, in
